* Move plugins under Channels
We move all plugin related fields under *Channels.
This essentially migrates several methods from being under
*Server to under *Channels.
We also move the plugin startup and shutdown code
to be under Channels.Start and Channels.Shutdown.
While here, we remove the getPluginPublicKeyFiles
method which was a one-line method which uselessly
returned an error.
Lastly, we fix the product initialization order which
was incorrect previously. Products are dependent on
the main server.
So startup should be products -> server.
And shutdown should be server -> products.

th.InitBasic initializes users, channels, and teams. But a lot of
tests don't use it at all, causing unncessary delays. A single InitBasic
call takes around 400ms. This PR removes 71 of them, approximately shaving
off 28 seconds. Arguably, this would be more because some tests run in loops.
