Make nova ephemeral storage backend configurable per-role

When multiple Compute roles are used, admins may want to use different storage
backends on each role.

This change turns NovaEnableRbdBackend into a role specific param.
Any other config that is implicitly enabled by the global NovaEnableRbdBackend
now requires a dedicated param.
