PERF: Disable Sidekiq only during database restore (#10857)
It pauses Sidekiq, clears Redis (namespaced to the current site), clears Sidekiq jobs for the current site, restores the database and unpauses Sidekiq. Previously it stayed paused until the end of the restore.

Redis is cleared because we don't want any old data lying around (e.g. old Sidekiq jobs). Most data in Redis is prefixed with the name of the multisite, but Sidekiq jobs in a multisite are all stored in the same keys. So, deleting those jobs requires a little bit more logic.

Gerhard Schlager ac70c48be4 FIX: Prevent "uploads are missing in S3" alerts after restoring a backup
After restoring a backup it takes up to 48 hours for uploads stored on S3 to appear in the S3 inventory. This change prevents alerts about missing uploads by preventing the EnsureS3UploadsExistence job from running in the first 48 hours after a restore. During the restore it  deletes the count of missing uploads from the PluginStore, so that an alert isn't triggered by an old number.

Krzysztof Kotlarek f530378df3 FIX: Restore for non-multisite is not raising an error on reconnect step (#8237)
That commit introduced a bug to the system: f69dacf979

Restore works fine for multisite, however, stopped working for non-multisite.

Reason for that was that `establish_connection` method got a check if the multisite instance is available:
```
    def self.instance
      @instance
    end

    def self.establish_connection(opts)
      @instance.establish_connection(opts) if @instance
    end
```
However, the reload method don't have that check
```
    def self.reload
      @instance = new(instance.config_filename)
    end
```

To solve it, let's ensure we are in a multisite environment before call reload

Krzysztof Kotlarek f69dacf979 FIX: Reconnect in restore process connects to correct DB (#8218)
Simplified flow of restore is like that
```
migrate_database
reconnect
extract_uploads
```

Problem with incorrect current database started with this fix https://github.com/discourse/discourse/commit/025d4ee91f4

Dump task is reconnecting to default database https://github.com/rails/rails/blob/master/activerecord/lib/active_record/railties/databases.rake#L429

And then, we are trying to reconnect to the original database with that code:
```
def reconnect_database
  log "Reconnecting to the database..."
  RailsMultisite::ConnectionManagement::establish_connection(db: @current_db)
end
```

This reconnect is not switching us back to correct database because of that check
https://github.com/discourse/rails_multisite/blob/master/lib/rails_multisite/connection_management.rb#L181
Basically, it finds existing handler and it thinks that we are connected to correct DB and this step can be skipped.

To solve it, we can reload RailsMultisite::ConnectionManagement which creates a new instance of that class
https://github.com/discourse/rails_multisite/blob/master/lib/rails_multisite/connection_management.rb#L38

Sam 5f64fd0a21 DEV: remove exec_sql and replace with mini_sql
Introduce new patterns for direct sql that are safe and fast.

MiniSql is not prone to memory bloat that can happen with direct PG usage.
It also has an extremely fast materializer and very a convenient API

- DB.exec(sql, *params) => runs sql returns row count
- DB.query(sql, *params) => runs sql returns usable objects (not a hash)
- DB.query_hash(sql, *params) => runs sql returns an array of hashes
- DB.query_single(sql, *params) => runs sql and returns a flat one dimensional array
- DB.build(sql) => returns a sql builder

Guo Xiang Tan 142571bba0 Remove use of `rescue nil`.
* `rescue nil` is a really bad pattern to use in our code base.
  We should rescue errors that we expect the code to throw and
  not rescue everything because we're unsure of what errors the
  code would throw. This would reduce the amount of pain we face
  when debugging why something isn't working as expexted. I've
  been bitten countless of times by errors being swallowed as a
  result during debugging sessions.
