NXCALS-1186 Replaces devdb11 service name with devdb11_nxcals
#Merge request template @acc-logging-team - please have a look for approval.
We have been given a new devdb11 connection service. It should be already available to all cern infrastructure machines via TNS name devdb11_nxcals. It is part of an effort from ITDB to provide us with a bit better QoS on the devdb11 space.
This MR replaces the overloaded devdb11 plain service name with the dedicated to nxcals one (devdb11_nxcals)
