Bug Description
We had configuration in nova-cloud-
it turned out that in an upgrade to stein the following filters which are now deprecated in stein were still selected in `juju config nova-cloud-
RamFilter,
Removing these filters led to healthy migrations again. In this particular case DiskFilter was blocking migrations
Could the charm go into a blocked or maintenance state with a warning that Deprecated filters of a certain release are configured and may impair migration

I don't think that the charm can police the filters as it might reject perfectly good ones if it's too stringent (e.g. a bug) and this would prevent usage in other scenarios.
However, I also hit a similar scenario with an Upgrade and wondered how I could find out, and what process we could suggest as part of an OpenStack upgrade.
Thus, this might be a documentation (what are the deprecations) and process (OpenStack upgrade) "look at xxx for notes of upgrade from x -> y" issue, rather than a charm issue.
Thoughts?
