* 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.
