Refactor Cloud Tools plugin into two and Moves Google-Login

This change refactors the Google Cloud Plugin into a base core plugin
and an Android (Studio) specific plugin.

It also moves Google-Login into our private git repo where it will
compile for IJ.

All three plugins (ctcore, ct4as, and login) now live under tools/studio/google/cloud

The repo under src/tools/studio/google/login should be removed.
There is an additional change to our ct4as plugin that removes all functionality
unrelated to android which is now included in our core IJ plugin.
