[Bug]: [T2 Chassis] 'test_snmp_lldp' test case fails on the latest master image

Issue Description

On the latest master image, for T2 Chassis, test case '_test_snmp_lldp_' fails, which checks for ieee802_1ab MIBs.

Results you see

For example, the following LLDP MIB queries are failing as part of the test,

    # From LLDP-MIB: lldpLocManAddrTables
    _self.lldpLocManAddrLen = dp + "1.0.8802.1.1.2.1.3.8.1.3"  # + .subtype + .man addr
    self.lldpLocManAddrIfSubtype = dp + \
        "1.0.8802.1.1.2.1.3.8.1.4"  # + .subtype + .man addr
    self.lldpLocManAddrIfId = dp + "1.0.8802.1.1.2.1.3.8.1.5"  # + .subtype + .man addr
    self.lldpLocManAddrOID = dp + "1.0.8802.1.1.2.1.3.8.1.6"  # + .subtype + .man addr_

Test failure shown below:

      # Check if lldpLocManAddrTable is present
       for k in ['lldpLocManAddrLen',
                  'lldpLocManAddrIfSubtype',
                  'lldpLocManAddrIfId',
                  'lldpLocManAddrOID']:
       assert snmp_facts['snmp_lldp'][k]
       E           KeyError: 'lldpLocManAddrLen'

Results you expected to see

'test_snmp_lldp' test case is expected to pass.

This test started failing after the PR #13115 has been taken, where lldp container is removed from host instances.

Is it platform specific

generic
