plex: add support for managing plugins via Nix

Browse source 
Added support for managing Plex plugins via Nix. This is done via an
"extraPlugins" configuration option which takes a list of paths to
plugin bundles, which are then symlinked into Plex's plugin directory
when the service is started.

A list of paths to extra plugin bundles to install in Plex's plugin
directory. Every time the systemd unit for Plex starts up, all of the
symlinks in Plex's plugin directory will be cleared and this module
will symlink all of the paths specified here to that directory. If
this behavior is undesired, set <option>managePlugins</option> to
false.
