In order to implement tests easier, `#select_tags` created.

This will allow Docker to be automatically check the health of services.

Docker won't do anything other than showing the state in the output of
"docker-compose ps" by default, but some management tools may watch for
container health events.

Here's what my local instance looks like right now:

          Name                        Command                  State                     Ports

* Add local followers page to admin account UI

For moderation, I often find myself wondering who, locally, is following
a remote user. Currently, to see this, I have to go back to the web UI,
paste in their full handle, click their profile, and go to the
"Followers" tab (plus, this information is incidental, and if mastodon
ever decides to resolve all of the follower information, there will be
no place local followers are shown). This PR adds a new page which is
accessible via the "following" count on the admin's account view
page, which shows the local followers. (It has filter parameters for
account location to indicate that only local followers are shown, and
leave room for expansion if mastodon ever decides to store the entire
remote follow list).
