FEATURE: Optional detailed performance logging for Sidekiq jobs (#7091)
By default, this does nothing. Two environment variables are available:

- `DISCOURSE_LOG_SIDEKIQ`

  Set to `"1"` to enable logging. This will log all completed jobs to `log/rails/sidekiq.log`, along with various db/redis/network statistics. This is useful to track down poorly performing jobs.

- `DISCOURSE_LOG_SIDEKIQ_INTERVAL`

  (seconds) Check running jobs periodically, and log their current duration. They will appear in the logs with `status:pending`. This is useful to track down jobs which take a long time, then crash sidekiq before completing.

Sam a19170a4c2 DEV: avoid require_dependency for some libs
This avoids require dependency on method_profiler and anon cache.

It means that if there is any change to these files the reloader will not pick it up.

Previously the reloader was picking up the anon cache twice causing it to double load on boot.

This caused warnings.

Long term my plan is to give up on require dependency and instead use:

FEATURE: Allow connecting associated accounts when two-factor is enabled (#6754)
Previously the 'reconnect' process was a bit magic - IF you were already logged into discourse, and followed the auth flow, your account would be reconnected and you would be 'logged in again'.

Now, we explicitly check for a reconnect=true parameter when the flow is started, store it in the session, and then only follow the reconnect logic if that variable is present. Setting this parameter also skips the 'logged in again' step, which means reconnect now works with 2fa enabled.

Sam 955cdad649 FIX: exec_params needs instrumentation
the method no longer routes to "exec" or "async_exec" in latest PG so we
need to explicitly intercept

Sam 379384ae1e FIX: never block /srv/status which is used for health checks
This route is also very cheap so blocking it is not required

It is still rate limited and so on elsewhere

- Drops `key` column from the `themes` table

- Adds `theme_ids` (array of ints default []) column to the `user_options` table and migrates data from `theme_key` to the new column.
- Removes the `default_theme_key` site setting and adds `default_theme_id` instead.
- Replaces `theme_key` cookie with a new one called `theme_ids`
- no longer need Theme.settings_for_client

Sam e72fd7ae4e FIX: move crawler blocking into anon cache

Sam ded84a4b58 PERF: improve performance once logged in rate limiter hits
If "logged in" is being forced anonymous on certain routes, trigger
the protection for any requests that spend 50ms queueing

This means that ...

1. You need to trip it by having 3 requests take longer than 1 second in 10 second interval
2. Once tripped, if your route is still spending 50m queueuing it will continue to be protected

This means that site will continue to function with almost no delays while it is scaling up to handle the new load

Sam 59cd7894d9 FEATURE: if site is under extreme load show anon view
If a particular path is being hit extremely hard by logged on users,
revert to anonymous cached view.

This will only come into effect if 3 requests queue for longer than 2 seconds
on a *single* path.

This can happen if a URL is shared with the entire forum base and everyone
is logged on
