Subject: [PATCH] Use json for subordinate configuration.

JSON encoding the subordinate config data is the preffered way to
pass it down the relation. This is supported by the corresponding
context https://github.com/juju/charm-helpers/blob/master/charmhelpers/contrib/openstack/context.py#L1272
and this is the approach cinder-ceph takes.
