Approach

What is the motivation for this PR?

Test added to use link local IP address as snmpagent address.

How did you do it?

Use ink local IP of eth0 IP address, configure that as MGMT address.
Restart SNMP service so that snmpd.conf uses newly assigned MGMT address as snmpagent address
Query using link local address
Check if snmpresult is as expected.
reload config to remove the MGMT link local IP assignment.

How did you verify/test it?

Verified on VS testbed,.

Any platform specific information?

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

@SuvarnaMeenakshi This is to add a new test. Do we really need it in 202205 branch?

@wangxin The change to support IPv6 SNMP is merged in 202205 and this change caused SNMP over link local IPv6 to fail.
As the change is added in 202205, it will be good to add this test in 202205 also.
@qiluo-msft any suggestion.
