Comment 9 for bug 1609688

I remember this issue involved several things:

* If mistral db-sync (or the part that fills the database with the openstack actions) fails, the errors are silently discarded.
  - We need this output in the logs.
* back then, the python-ironic-inspector required a working keystone in order to be created, if keystone is not available when this command is ran, it won't be able to create a client instance, and the dynamic creation of actions will fail. So we need keystone to be available before both ironic-inspector and before mistral.
