SNMP assumes the first half of the queues to be unicast and the second half to be multicast. This assumption was fine for most hwSkus but not new ones being added to support, i.e. x86_64-arista_7060x6.
This change will allow configurations where there are more than half of maximum queues set as unicast. It however does not account for the case where there are more than half of the maximum queues set as multicast - that will cause problems for the sonic-mgmt snmp/test_snmp_queue.py test.

Note:
Only tested on Arista hwSkus.
What I did
Accommodate for the case where the number of Unicast queues exceed the number of Multicast queues.
How I did it
Allow Unicast queues to be added to response when their queue number is greater than half of the total number of queues.
How to verify it
Passing unit tests and SNMP tests in sonic-mgmt. Note: Only ran on Arista hwSkus
