CPS-1126 : CmHandle creation performance degradation

References:

CPS-1126 - Getting issue details... STATUS

Overview :

With previous versions we were able to register 10k cmhandles (in 4 threads) in 12 minutes.
With the current CPS master we sent the 10k cmHandles  around 10 minutes to NCMP, so it is not faster than before. What I see is that NCMP starts getting modules in a background thread (seems to be one thread) and handling one cmhandle takes more seconds.
Currenlty in 12 minutes only 150 cmHandles got available with ready state in NCMP, because getting modules and changing the state is quite slow this way. 

Expected behavior
With previous versions we were able to register 10k cmhandles (in 4 threads) in 12 minutes.

Reproduction

Register huge amount of cmhandles and try to search them.
After 12 minutes there were only ~150cmHandles inready state

Analyzed the logs the summary is as below :
