Mark the LVM backend as stateful rather than stateless
The cinder-lvm charm was registering the backend configuration with the
principal charm as stateless when it is indeed stateful. Change
I249ce179cfdaf2394ee4e8481a8c9644d667ea99 introduced the cluster
configuration for the cinder service which causes backend drivers which
are not properly marked as stateful to fail. Correct the stateless value
in the charm to indicate this.
Add the 'volume-group' and 'backend-name' config parameters
In order to ease transition into cinder-lvm, we need these 2 parameters
so that the new charm can be configured with the exact same names as
what cinder was using, avoiding any potential data loss and without
the need for workarounds such as playing with the 'alias' or 'overwrite'
configuration options.
This patchset does the following things:
- Implements the unit tests.
- Standardizes the charm, adding the needed files and moving
pre-existing ones into the correct directories.
- Implements the bundles for functional tests.
- Documents the charm's functionality.
- Updates the requirements for tests and other targets.
we should be using "extend-ignore" instead of "ignore" in the [flack8]
section so that those options are _added_ to the current ignore list
instead of replacing it.
This was causing problems on tests because default ignore list has W503
and W504 listed, which are contradictory and create an impossible
situation if both are enabled and the override was enabling them again.
