Automatically add `moderators` and `admins` auto groups to specific site settings.
In the new group-based permissions systems, we just want to check the user’s groups since it more accurately reflects reality

* DEV: Add rake command to help detect dead settings
Some Site Settings may still exist but are no longer being used in the
core discourse code or in related plugins. This rake task will help
identify any unused (aka: dead) settings by using the `rg` command to
search for them.
You can execute the rake task by using this command:
`LOAD_PLUGINS=1 bin/rails "site_settings:find_dead"`
* Add env variable, apply feedback
To add an extra layer of security, we sanitize settings before shipping them to the client. We don't sanitize those that have the "html" type.
The CookedPostProcessor already uses Loofah for sanitization, so I chose to also use it for this. I added it to our gemfile since we installed it as a transitive dependency.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
