FIX: Reopen sidekiq log files after rotation (#9429)
Unicorn uses the USR1 to indicate that log files should be reopened. This commit implements the same functionality for our forked sidekiq workers:

- USR1 is intercepted in the unicorn master, and re-issued to all child processes
- USR1 is trapped in the sidekiq processes, and `Unicorn::Util.reopen_logs` is used to re-open log files

PERF: avoid shelling to get hostname aggressively
Previously we had many places in the app that called `hostname` to get
hostname of a server. This commit replaces the pattern in 2 ways

1. We cache the result in `Discourse.os_hostname` so it is only ever called once

2. We prefer to use Socket.gethostname which avoids making a shell command

This improves performance as we are not spawning hostname processes throughout
the app lifetime

Sam Saffron f5396e2700 DEV: Sidekiq::Logging is gone use Sidekiq.logger instead
This 6.0 upgrade of sidekiq moved this around.

Krzysztof Kotlarek 35b1185a08 FIX: Revert Demon::DemonBase back to Demon::Base (#8132)
I introduced DemonBase because I had got some conflict between `demon/base.rb` and `jobs/base.rb`, however, to not rename base class, it is possible to use regex on absolute path in Zeitwerk custom inflector.

Krzysztof Kotlarek 427d54b2b0 DEV: Upgrading Discourse to Zeitwerk (#8098)
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains. 

We no longer need to use Rails "require_dependency" anywhere and instead can just use standard 
Ruby patterns to require files.

This is a far reaching change and we expect some followups here.

Sam Saffron 30990006a9 DEV: enable frozen string literal on all files
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

Sam 384135845b FEATURE: introduce ultra_low priority queue
This commit introduces an ultra low priority queue for post rebakes. This
way rebakes can never interfere with regular sidekiq processing for cases
where we perform a large scale rebake.

Additionally it allows Post.rebake_old to be run with rate_limiter: false
to avoid triggering the limiter when rebaking. This is handy for cases
where you want to just force the full rebake and not wait for it to trickle

Sam df460b4abd PERF: run sidekiq with nice 5
This ensures that unicorn master forks of sidekiq run with a lower priority
than the webs. It means that a busy sidekiq is less likely to impact web
performance

Sam 8ec7fd84fd FEATURE: prioritize sidekiq jobs
This commit introduces 3 queues for sidekiq

"critical" for urgent jobs (weighted at 4x weight)
"default" for standard jobs(weighted at 2x weight)
"low" for less important jobs


"critical jobs"

Reset Password emails has been seperated to its own job
Heartbeat which is required to keep sidekiq running
Test email which needs to return real quick


"low priority jobs"

Notify mailing list
Pull hotlinked images
Update gravatar

"default"

All the rest

Note: for people running sidekiq from command line use

bin/sidekiq -q critical,4 -q default,2 -q low
