Comment 12 for bug 1746548

I'm going to mark this bug as Invalid; we change the way ceilometer does its upgrade task to be action oriented as its pretty much impossible to get an in-hook upgrade to work with so many downstream charm dependencies:

   gnocchi
     |----- keystone ---- mysql
     |----- mysql
     |----- ceph-mon ---- ceph-osd
     |----- memcached

Hence its an external action driven task now.

We might get to this once goal-state is full adopted but that's not going to be for a few cycles yet.
