Issue:
Issue Rif Counters can not work when removing one router interface sonic-net#729

Issue scenario:
1- create some RIFs if no RIF exist
2- remove all RIFs
3- add new RIF
4- RIF counters are not working for new RIF

Root cause:
Occurred at step sonic-net#2.
In function FlexCounter::removeRif in 201911 branch, removing the whole instance leads to RIF flex counter group to be removed.
After that when adding a new RIF, RIF flex counter group will be created again with zero poll interval
As a result zero poll interval RIF thread will not started and therefore the counters table will not filled up.
The symptom is N/A values in "show interfaces counters rif" command.

Fix:
Instead of removing the whole instance, will remove the counter from the m_collectCountersHandlers.
