We want to default to running all tox environments under python 3, so set the basepython value in each environment. We do not want to specify a minor version number, because we do not want to have to update the file every time we upgrade python. We do not want to set the override once in testenv, because that breaks the more specific versions used in default environments like py35 and py36.

Ceph Storage Backend for Cinder
Overview
This charm provides a Ceph storage backend for use with the Cinder charm; this allows multiple Ceph storage clusters to be associated with a single Cinder deployment, potentially alongside other storage backends from other vendors.
To use:
juju deploy cinder
juju deploy -n 3 ceph
juju deploy cinder-ceph
juju add-relation cinder-ceph cinder
juju add-relation cinder-ceph ceph
Configuration
The cinder-ceph charm allows the replica count for the Ceph storage pool to be configured. This must be done in advance of relating to the ceph charm:
juju set cinder-ceph ceph-osd-replication-count=3
juju add-relation cinder-ceph ceph
By default, the replica count is set to 2 replicas. Increasing this value increases data resilience at the cost of consuming most real storage in the Ceph cluster.
