gerrit: Initalize in testing

By setting the auth type to DEVELOPMENT_BECOME_ANY_ACCOUNT and passing
--dev to the init process, gerrit will create an initial admin user
for us.  We leverage this user to create a sample project, change,
Zuul user and sample CI result comment.

We also update testinfra to take some screenshots of gerrit and report
them back.
