need to lock running as well as candidate config in mounted device

when modifying the configuration of a mounted device in response to a RESTCONF PUT or POST request ODL locks the candidate configuration, however it doesn't lock the running configuration.

this risks a race condition where the running configuration is edited by another user (e.g. from the CLI) before ODL commits the configuration changes.

is it possible to apply a lock to the running configuration as well as the candidate configuration?
