[Telemetry][TC]Telemetry status


I can  volounteer to spend time on Ceilomter and Gnocchi while I have 
some mimimal knowledge on Ceilomter
and pretty much none on the Gnocchi codebase I would like to see the 
project continued.

Another thing would be if Gnocchi should be moved back or if I should 
somehow get in contact with the former
Gnocchi maintainers and see if we can get access to GitHub?

Best regards
