Split reviewers plugin into GWT and non-GWT variants
The UI portions have not yet been ported to PolyGerrit, but the plugin
is still useful with no UI, particularly for auto-adding reviewers.
Split the Module file into a ClientModule and BackendModule, and leave
Module as simple wrapper that delegates to both of them. The
backend-only plugin's code lives entirely in the server directory, and
is factored out into a new plugin named reviewers-backend.
The combined Module, its gwt.xml file, as well as its GWT-specific code
(e.g. the top menu) must live directly above the "client" directory,
otherwise the GWT build fails with a mysterious error.
The gerrit_plugin rule needs to be tweaked slightly to allow multiple
rules in the same BUILD file, not all of which match the directory name.
