Unskip devstack-admin-plugins job

The job was failing because of a bug described in the launchpad [1].
As this bug is resolved and the job is no longer failing we can
start using this job again.

Before enabling the devstack-admin-plugins job we need to fix two
things:

- Put test_manually_trigger_update_secondary_zone_negative designate
  plugin test to exclude_regex as it is currently broken.

- Allow git to read plugins directories. This is necessary because
  of a patch that was recently added to git [2].
