This patch removes the `with_service` helper from the code base.
Instead, we can pass a block with actions directly to the `.call` method
of a service.
This simplifies how to use services:
- use `.call` without a block to run the service and get its result
object.
- use `.call` with a block of actions to run the service and execute
arbitrary code depending on the service outcome.
It also means a service is now “self-contained” and can be used anywhere
without having to include a helper or whatever.
A new setting attribute is used to define the areas (separated by `|`).
In addition, endpoint `/admin/config/site_settings.json` accepts new `filter_area` data.
### Why?
Before, all flags were static. Therefore, they were stored in class variables and serialized by SiteSerializer. Recently, we added an option for admins to add their own flags or disable existing flags. Therefore, the class variable had to be dropped because it was unsafe for a multisite environment. However, it started causing performance problems.
### Solution
When a new Flag system is used, instead of using PostActionType, we can serialize Flags and use fragment cache for performance reasons.
At the same time, we are still supporting deprecated `replace_flags` API call. When it is used, we fall back to the old solution and the admin cannot add custom flags. In a couple of months, we will be able to drop that API function and clean that code properly. However, because it may still be used, redis cache was introduced to improve performance.
To test backward compatibility you can add this code to any plugin
```ruby
replace_flags do |flag_settings|
flag_settings.add(
4,
:inappropriate,
topic_type: true,
notify_type: true,
auto_action_type: true,
)
flag_settings.add(1001, :trolling, topic_type: true, notify_type: true, auto_action_type: true)
end
```

Followup 4aea12fdcb
In certain config areas (like About) we want to be able
to fetch specific site settings by name. In this case,
sometimes we need to be able to fetch hidden settings,
in cases where a config area is still experimental.
Splitting out a different endpoint for this purpose
allows us to be stricter with what we return for config
areas without affecting the main site settings UI, revealing
hidden settings before they are ready.
This commit continues work laid out by ffec8163b0 for the admin config page for the /about page. The last commit set up the user interface, and this one sets up all the wiring needed to make the input fields and save buttons actually work.

Continued work on moderate flags UI.
In this PR admins are allowed to change the order of flags. The notify user flag is always on top but all other flags can be moved.
This commit removes the `/admin-revamp` routes which were introduced as a part of an experiment to revamp the admin pages. We still want to improve the admin/staff experience, but we're going to do them within the existing `/admin` routes instead of introducing a completely new route.
Our initial efforts to improve the Discourse admin experience is this commit which introduces the foundation for a new subroute `/admin/config` which will house various new pages for configuring Discourse. The first new page (or "config area") will be `/admin/config/about` that will house all the settings and controls for configuring the `/about` page of Discourse.
