Storage Subordinate / Interface

[Chris MacNaughton]

Hey Juju folks,

I'm considering a new Juju subordinate charm / interface that would 
provide storage with pluggable backends. In essence, this subordinate 
would provide the storage interface, which would expose a mount point to 
the associated charm. In the other end, it would require the interfaces 
for ceph-client, gluster, and potentially other backing stores.

An example charm use would be:

The PostgresQL charm would no longer need the ceph-client relation, it 
would merely need to to require the storage interface.

Any interest in something like this?
