The error reporte when moving channels and failing has been improved to show
that the problem was the repeated name on the team.
The error message has been unified with MM-53756

Previously, we relied on the plugin to close the DB connections
on shutdown. While this keeps the code simple, there is no guarantee
that the plugin author will remember to close the DB.
In that case, it's better to track the connections from the server side
and close them in case they weren't closed already. This complicates
the API slightly, but it's a price we need to pay.
https://mattermost.atlassian.net/browse/MM-56402
```release-note
We close any remaining unclosed DB RPC connections
after a plugin shuts down.

* MM-57018: support reattaching plugins
Expose a local-only API for reattaching plugins: instead of the server starting and managing the process itself, allow the plugin to be launched externally (eg within a unit test) and reattach to an existing server instance to provide the unit test with a fully functional RPC API, sidestepping the need for mocking the plugin API in most cases.
In the future, this may become the basis for running plugins in a sidecar container.
Fixes: https://mattermost.atlassian.net/browse/MM-57018
* drop unused supervisor.pid
* factor out checkMinServerVersion
* factor out startPluginServer
* restore missing setPluginState on successful reattach
* avoid passing around a stale registeredPlugin
* inline initializePluginImplementation
* have IsValid return an error
* explicitly close rpcClient
In the case of reattached plugins, the Unix socket won't necessarily disappear leaving the muxBrokers blocked indefinitely. And `Kill()` doesn't do anything if there's no process being managed.
* explicitly detachPlugin
* emphasize gRPC not being supported

- Bump timeouts for some cases
- Improve sleep with require/assert.EventuallyT
for better performance and reliability.
https://mattermost.atlassian.net/browse/MM-57532
```release-note
NONE
```
Improvements to logging start-up.
- comments have been added
- order of configuration is adjusted to allow the main logger to capture errors in notification logger
- redundant logger initialization removed; no need to configure the logger just to replace the configuration immediately after
Previous log lines just had generic errors
which made things difficult to debug because
if a system bot is disabled, it's hard to know
whether the error is coming while trying to send
post reminders or from some other part of the system.
```release-note
NONE
```

* add comment to GetLRUSessions
* add limit to oauth path; PR comments
* Use a row constructor comparison to avoid a filter
The original query had a WHERE condition that looked like:
(x > a) OR (x = a AND y < b)
This commit changes it to a compound comparison that, given the
lexicographical order it uses, is semantically the same:
(x, y) > (a, b)
This makes the plan in Postgres use an Index Cond instead of a Filter,
having two main performance improvements:
1. The query's time is more or less constant, not increasing every time
this query is executed. This is important because the query is executed
repeatedly until all posts are indexed.
2. The query's time is much shorter: while the original query eventually
takes 30s, hitting the timeout, the new one takes ~30ms.
Notice the difference in the plans below:
- the original query uses a `Filter` step, while the new one uses an
`IndexCond` + `Filter` step.
- the original query has a shared hit count of 40557115 (109GiB), while
the new one has a shared hit count of 13951 (109MiBA). This does not
show exactly how much data is read from disk, given it's a nested loop
node, but it gives us an idea of the amount of data processed in the
server.

* Go back to the old query for MySQL
As one could expect, the two databases have completely opposite
behaviours, and for MySQL, the old query is significantly faster than
the new one, exactly for the same reason than in Postgres, but the other
way around: the old query uses an Index range scan while the new one
would use a Filter.
