A change was done in puppet-ironic:
https://review.openstack.org/#/c/457478/
It broke TripleO upgrades because ironic-dbsync.log used to be owned by
root:root and now it's managed by ironic user in puppet-ironic, which is
good.
Because we want to support existing deployments, we need a way to handle
the new owership change, so let's do it in a upgrade task in
undercloud.py. Puppet will be able to run ironic-dbsync and we'll remove
this workaround after Pike release.
Newton backport note:
Since the Newton version does not have "upgrade" flag passed to install,
a try..except block was added to handle fresh installations, where
the affected file does not exist.
