Our current Ceilometer driver relies on old version of ceilometer client,
which is in deprecated state and not compatible with the latest Telemetry
projects (Panko, Gnocchi). The functionality of the driver is not tested
automatically and most probably broken. So it's time to let it go and
clean the code.
This patch leaves "messaging" driver as default for notification and
makes "connection-string" a required parameter in CLI. In the future
we may consider to change default notification driver, though it
requires proper release note handling in all affected projects.
