[202012] Disable ALPM distributed hitbit thread that is used for debug purpose only but interfered with Other functional operations (#9190)

Browse Source 
This is to address an issue where it was observed that SAI operations sometime make take a very long to time complete (over 45ms). It was determined that the ALPM distributed thread was causing this issue.
The fix is to disable this debug thread that has no functional purpose.

Preliminary tests looks fine. BGP neighbors were all up with proper routes programmed
interfaces are all up
Manually ran the fib test cases on 7050CX3 (TD3), TD2, TH, TH2, and TH3 based platforms and
thy all passed.
