CI: Add scripts to (in)activate carriers on VVDN

Add vvdn-activate-carriers.sh to verify RU PTP synchronization and
configuration. Activates carriers on VVDN RU by editing sysrepo running
datastore (INACTIVE->ACTIVE).

Add vvdn-inactive-carriers.sh to reverse the operation, setting all
carriers back to INACTIVE via sysrepocfg.
