Add option to add config under [cinder-ceph]

Bug Description

Add option to add config under [cinder-ceph], currently, you can only add custom values under [DEFAULTS] however when I tried to enable image_volume_cache it needs to be added under a backed where you want to use it, [cinder-ceph] in my example. In order not to change cinder.conf manually so Juju won't wipe my change if I do any juju config, I've tried to do cinder.conf.d similar to what you can do with nova.conf.d. However, I don't think cinder search for conf.d as I couldn't get it to work only when I manually added the following changes in cinder.conf I've got cached enabled.

image_volume_cache_enabled = True

It would be good if you could add some sort regex or search that if the following section/key-value pair is found then replace it or add it, in this case, you could have your extra customization within Juju deployment.

While this feature seems to be about a generic request to be able to add config into backend config sections, it should be noted that support for Cinder's image caching just landed in the cinder charm:

Thanks, I'll give it a go, but still, I think it would be useful to have a more generic way of "If you know what you doing" configuration.
