Bug description:
  Trying to enable the dashboard module in ceph-mrg according to this
  guide https://blog.widodh.nl/2017/06/using-the-new-dashboard-in-ceph-
  mgr/ I'm seeing an error in the ceph-mgr log during startup:

  Expected result (seen after installing python-jinja2 pkg):

  So that package should be added as dependency to ceph-mgr.
