Add buffer queue counters test case to telemetry test

[arfeigin]

Description of PR

This test is checking that the number of buffer queue counters from telemetry point of view is inline when using create_only_config_db_counters optimization.

Summary:
Accompanies "Fix SNMP dropping some of the queue counter when create_only_config_db_buffers is set to true" (sonic-net/sonic-snmpagent#303) which fixes the issue: "The feature "polling only configured ports buffer queue" will break SNMP" (sonic-net/sonic-buildimage#17448).
Accompanies "Test polling only configured buffer queue counters" #11941

Approach

What is the motivation for this PR?

To enhance the bug fix mentioned above, solving an issue with buffer queue counters optimization.

How did you do it?

• Set "create_only_config_db_buffers" to true in config db, to create only relevant counters
• Remove one of the buffer queues, Ethernet0|3-4 is chosen arbitrary
• Using gnmi to query COUNTERS_QUEUE_NAME_MAP for Ethernet0 compare number of queue counters on Ethernet0. It is expected that it will decrease by the number of deleted queue buffers.

How did you verify/test it?

Run the test multiple times on various setups.

Any platform specific information?

Supported testbed topology if it's a new test case?

Any
