* MM-37165: Fix improper plugin shutdown
This was caught from a race test failure. While the failure manifested due to a log being
written from a test after the test exited, the real reason was hidden further deeper.
What was happening is that the server would always listen for plugin requests in a
separate goroutine via `g.muxBroker.AcceptAndServe` in the `OnActivate` hook. But the
plugin shutdown process would just close the plugin connections and move on, leading
to the classic case of improperly shut down goroutines.
When this happened, an opportunity opens up in a way that the server
would still be executing a request whereas the main goroutine and therefore the parent
test has already finished. This would lead to an error like
```
{"level":"error","ts":1626451258.4141135,"caller":"mlog/sugar.go:25","msg":"pluginAPI scheduleOnce poller encountered an error but is still polling","plugin_id":"com.mattermost.plugin-incident-management","error":"ListPluginKeys: Unable to list all the plugin keys., failed to get PluginKeyValues with pluginId=com.mattermost.plugin-incident-management: sql: database is closed
```
And now, this finally calls `mlog.Error`, which finally triggers our race condition :)
To fix this, we use some basic synchronization via waitgroups and just wait for it
to finish after closing the plugin process.

* MM-37575: Handle nil value in override_username
Since props is a map[string]interface{}, an ", ok" check doesn't
really help because even if a key is not present, by default, a map
will always return the default value of the value, which would be a
nil interface.
So we can just check for the value of the map instead.

We used to log an error and move forward, which led to
panics later during server execution, because the templates
don't exist.
While technically speaking the server will run fine
because it's just one HTTP handler goroutine which panics,
but properly handling the error requires much more adjustments
in the code to check for nil templates.
It is better to fail earlier and force the application
to start in a clean slate.

Summary
If a user has unfollowed a thread, another user's reply in the thread should not cause the first user to re-follow the thread. The first user will be re-followed if they are mentioned in the thread.
Simplify and make flexible the logic surrounding following and remove some duplicate code.

* MM-25516: Changed to byte slice instead of string for cluster messages
https://mattermost.atlassian.net/browse/MM-25116
Testing:
Manually tested.
Load-tested with Cluster Controller.
I looked into changing the serialization method to use msgpack,
but the ClusterMessage struct was mainly used for only 3 fields
which didn't lead to much of a CPU time improvement, whereas
actually led to more allocations using msgpack. Hence, I chose
to remain with JSON.
```
name old time/op new time/op delta
ClusterMarshal-8 3.51µs ± 1% 3.10µs ± 2% -11.59% (p=0.000 n=9+10)
name old alloc/op new alloc/op delta
ClusterMarshal-8 776B ± 0% 1000B ± 0% +28.87% (p=0.000 n=10+10)
name old allocs/op new allocs/op delta
ClusterMarshal-8 12.0 ± 0% 13.0 ± 0% +8.33% (p=0.000 n=10+10)
```

We replace the double conversion of
[]byte to string, with a direct write
to http.ResponseWriter.

Tried using gofmt -r, but it only accepts Go
expressions. So had to resort to an ugly sed replace
sed -E -i 's/w.Write\(\[\]byte\((.*).ToJson\(\)\)\)/if err := json.NewEncoder\(w\).Encode\(\1\); err != nil { mlog.Warn\("Error while writing response", mlog.Err\(err\)\)}/g' *.go
