3d1bbf7446 FIX: Logout could fail due to cached user
Logging out failed when the current user was cached by an instance of `Auth::DefaultCurrentUserProvider` and `#log_off_user` was called on a different instance of that class.

61ed83ecfc FIX: Incorrect currentUser could be cached for requests with API key (#17279)
This happened when a middleware accessed the `currentUser` before a controller had a chance to populate the `action_dispatch.request.path_parameters` env variable. In that case Discourse would always cache `nil` as `currentUser`.

DEV: Introduce Auth::Result API for overrides_* (#15378)
This allows authenticators to instruct the Auth::Result to override attributes without using the general site settings. This provides an easy migration path for auth plugins which offer their own "overrides email", "overrides username" or "overrides name" settings. With this new api, they can set `overrides_*` on the result object, and the attribute will be overriden regardless of the general site setting.

ManagedAuthenticator is updated to use this new API. Plugins which consume ManagedAuthenticator will instantly take advantage of this change.

FEATURE: Experimental support for group membership via google auth (#14835)
This commit introduces a new site setting "google_oauth2_hd_groups". If enabled, group information will be fetched from Google during authentication, and stored in the Discourse database. These 'associated groups' can be connected to a Discourse group via the "Membership" tab of the group preferences UI. 

The majority of the implementation is generic, so we will be able to add support to more authentication methods in the near future.

FEATURE: Apply rate limits per user instead of IP for trusted users (#14706)
Currently, Discourse rate limits all incoming requests by the IP address they
originate from regardless of the user making the request. This can be
frustrating if there are multiple users using Discourse simultaneously while
sharing the same IP address (e.g. employees in an office).

This commit implements a new feature to make Discourse apply rate limits by
user id rather than IP address for users at or higher than the configured trust
level (1 is the default).

For example, let's say a Discourse instance is configured to allow 200 requests
per minute per IP address, and we have 10 users at trust level 4 using
Discourse simultaneously from the same IP address. Before this feature, the 10
users could only make a total of 200 requests per minute before they got rate
limited. But with the new feature, each user is allowed to make 200 requests
per minute because the rate limits are applied on user id rather than the IP
address.

The minimum trust level for applying user-id-based rate limits can be
configured by the `skip_per_ip_rate_limit_trust_level` global setting. The
default is 1, but it can be changed by either adding the
`DISCOURSE_SKIP_PER_IP_RATE_LIMIT_TRUST_LEVEL` environment variable with the
desired value to your `app.yml`, or changing the setting's value in the
`discourse.conf` file.

Requests made with API keys are still rate limited by IP address and the
relevant global settings that control API keys rate limits.

Before this commit, Discourse's auth cookie (`_t`) was simply a 32 characters
string that Discourse used to lookup the current user from the database and the
cookie contained no additional information about the user. However, we had to
change the cookie content in this commit so we could identify the user from the
cookie without making a database query before the rate limits logic and avoid
introducing a bottleneck on busy sites.

Besides the 32 characters auth token, the cookie now includes the user id,
trust level and the cookie's generation date, and we encrypt/sign the cookie to
prevent tampering.

Internal ticket number: t54739.

FIX: Don't leak unhashed user API keys to redis (#14682)
User API keys (not the same thing as admin API keys) are currently
leaked to redis when rate limits are applied to them since redis is the
backend for rate limits in Discourse and the API keys are included in
the redis keys that are used to track usage of user API keys in the last
24 hours.

This commit stops the leak by using a SHA-256 representation of the user
API key instead of the key itself to form the redis key.

We don't need to manually delete the existing redis keys that contain
unhashed user API keys because they're not long-lived and will be
automatically deleted within 48 hours after this commit is deployed to
your Discourse instance.

FEATURE: Allow parameter authentication for UserApiKeys (#9742)
This refactors default_current_user_provider in a few ways:
- Introduce a generic `api_parameter_allowed?` method which checks for whitelisted routes/formats
- Only read the api_key parameter on allowed routes. It is now completely ignored on other routes (previously it would raise a 403)
- Start reading user_api_key parameter on allowed routes
- Refactor tests as end-end integration tests

A plugin API for PARAMETER_API_PATTERNS will be added soon

DEPRECATION: Remove support for api creds in query params (#9106)
* DEPRECATION: Remove support for api creds in query params

This commit removes support for api credentials in query params except
for a few whitelisted routes like rss/json feeds and the handle_mail
route.

Several tests were written to valid these changes, but the bulk of the
spec changes are just switching them over to use header based auth so
that they will pass without changing what they were actually testing.

Original commit that notified admins this change was coming was created
over 3 months ago: 2db2003187

* fix tests

* Also allow iCalendar feeds

FEATURE: Stricter rules for user presence
Previously we would consider a user "present" and "last seen" if the
browser window was visible.

This has many edge cases, you could be considered present and around for
days just by having a window open and no screensaver on.

Instead we now also check that you either clicked, transitioned around app
or scrolled the page in the last minute in combination with window
visibility

This will lead to more reliable notifications via email and reduce load of
message bus for cases where a user walks away from the terminal

FEATURE: Send notifications for time-based and At Desktop bookmark reminders (#9071)
* This PR implements the scheduling and notification system for bookmark reminders. Every 5 minutes a schedule runs to check any reminders that need to be sent before now, limited to **300** reminders at a time. Any leftover reminders will be sent in the next run. This is to avoid having to deal with fickle sidekiq and reminders in the far-flung future, which would necessitate having a background job anyway to clean up any missing `enqueue_at` reminders.

* If a reminder is sent its `reminder_at` time is cleared and the `reminder_last_sent_at` time is filled in. Notifications are only user-level notifications for now.

* All JavaScript and frontend code related to displaying the bookmark reminder notification is contained here. The reminder functionality is now re-enabled in the bookmark modal as well.

* This PR also implements the "Remind me next time I am at my desktop" bookmark reminder functionality. When the user is on a mobile device they are able to select this option. When they choose this option we set a key in Redis saying they have a pending at desktop reminder. The next time they change devices we check if the new device is desktop, and if it is we send reminders using a DistributedMutex. There is also a job to ensure consistency of these reminders in Redis (in case Redis drops the ball) and the at desktop reminders expire after 20 days.

* Also in this PR is a fix to delete all Bookmarks for a user via `UserDestroyer`

9ebabc1de8 FEATURE: unconditionally update Topic updated_at when posts change in topic
Previously we would bypass touching `Topic.updated_at` for whispers and post
recovery / deletions.

This meant that certain types of caching can not be done where we rely on
this information for cache accuracy.

For example if we know we have zero unread topics as of yesterday and whisper
is made I need to bump this date so the cache remains accurate

This is only half of a larger change but provides the groundwork.

Confirmed none of our serializers leak out Topic.updated_at so this is safe
spot for this info

At the moment edits still do not change this but it is not relevant for the
unread cache.

This commit also cleans up some specs to use the new `eq_time` matcher for
millisecond fidelity comparison of times

Previously `freeze_time` would fudge this which is not that clean.

  -H "Content-Type: multipart/form-data;" \
  -H "Api-Key: 7aa202bec1ff70563bc0a3d102feac0a7dd2af96b5b772a9feaf27485f9d31a2" \

  -F "color=49d9e9" \

```

instead of specifying the username along with the key.
