This PR adds functionality to search by a global search prefix.
This allows Mattermost to be used across multiple data centers
with multiple Elasticsearch instances synchronized using
cross-cluster replication.
While here, we also add tests cases to cover for some missing
search interface methods.
For now, no system console setting is exposed. Because IndexPrefix
is also not exposed. It can be added later if a need arises.
https://mattermost.atlassian.net/browse/MM-63298
```release-note
A new config setting ElasticsearchSettings.GlobalSearchPrefix is added
which can be used to search across multiple indices having a common prefix.
This is useful in a scenario with multiple Elasticsearch instances, where
multiple instances are writing to different indices with different prefixes
using the ElasticsearchSettings.IndexPrefix setting.

- Replace golint with revive
- Add makezero linter
- Fix all the required linter failures
Some issues in enterprise and public modules
are yet to be fixed. We send this to expediate things.
It was a good decision in hindsight to keep the public module as 0.x
because this would have been a breaking change again.

```release-note
Changed the Go module path from github.com/mattermost/mattermost-server/server/v8 to github.com/mattermost/mattermost/server/v8.
For the public facing module, it's path is also changed from github.com/mattermost/mattermost-server/server/public to github.com/mattermost/mattermost/server/public

* MM-45956: Optimize FileInfo stats query
We Denormalize Post.ChannelId on FileInfo.ChannelId
```release-note
The file info stats query is now optimized by denormalizing the channelID column into the table itself. This will speed up the query to get the file count for a channel on clicking the RHS.
Migration times:
On a MySQL 8.0.31 DB with
1405 rows in FileInfo and 11M posts, it took around 0.3s
On a Postgres 12.14 DB with
1731 rows in FileInfo and 11M posts, it took around 0.27s
