Title: Support Multisite by custom activation logic to set the default GCS bucket

This plugin sets the default GCS bucket on activation via an action registered via `register_activation_hook`. `register_activation_hook` is not called in Network installs of wordpress or for mu-plugins.

This pull request uses an installation guard via `get_option` and `add_option` to make sure it only runs once for each blog.
