multi-series subordinates just don't work

[Marco Ceppi]

When deploying subordinates that declare trusty and xenial, Juju does not allow adding a relation to both of those from a single charm. Instead default series is used which limits the flexibility of cross series relations.

This should not be the case given the charms declare support for cross series. In order to keep a clean simple model this should be adjusted for subordinates.

Just being realistic about what we are and aren't working on.

[Tim Penhey (thumper)]

The subordinate shouldn't store the series against it's application in the DB. The series should be determined at relation join time for that relationship.

The issue presented in this bug report doesn't hold anymore as I understand it. That is, 2 deployed primaries of different series can, in fact, relate to the same subordinate (if it supports those series). Likewise, 2 Deployed subordinates of different series can relate to the same primary (if it supports those series). As such, I am going to mark this bug report as incomplete pending further information.

Thanks for verifying it works. I'm going to mark it as fix committed as this was a change done by Ian in 2.5.
