This updates the README for erasure coded
Ceph pools for the case of Ceph-backed Glance.
The new text should be as similar as possible
for all the charms that support configuration
options for EC pools. See the below review for
the first of these charms whose README has been
updated.
* charm-helpers sync for classic charms
* charms.ceph sync for ceph charms
* rebuild for reactive charms
* sync tox.ini files as needed
* sync requirements.txt files to sync to standard
Adds multi-backend support to Glance. Currently supported backends
are local, Swift and RBD. The order of preference for default backend
is RBD --> Swift --> Local. Backend can be selected explicitly by the
operator when creating an image.
