This stops an error that happens when size is not
specified when adding storage via Juju storage hooks.
Without a set minimum, Juju will give 1G to a disk
which will cause ceph-disk to fail when connecting
the new disk.

This optimizes the publication process to the charm store, and
ensures that the charm code and version is consistent across all
supported Ubuntu series.

This adds support for Juju's storage hooks by merging the config
provided osd-devices with Juju storage provided osd-devices, in the
same way that the existing Ceph charm handles them.

In addition to providing support for ceph-osds via Juju storage,
we provide support for multiple journal devices through Juju storage
as well.

We have to add a shim hook to ensure that Ceph is installed prior
to storage hook invocation because storage attached at deploy time
will execute hooks before the install hook

Juju 2.0 provides support for network spaces, allowing
charm authors to support direct binding of relations and
extra-bindings onto underlying network spaces.

Add public and cluster extra bindings to this charm to
support separation of client facing and cluster network
traffic using Juju network spaces.

Existing network configuration options will still be
preferred over any Juju provided network bindings, ensuring
that upgrades to existing deployments don't break.
