Revert "[rfc1213] Interface MIB add l3 vlan interfaces & aggregate rif counters (#169)" (#191)

**- What I did**
Revert all drop SNMP counters issue. Because it introduces inconsistency with RFC2863

**- How I did it**
Revert 3 commits related to this feature.

**- How to verify it**
The RFC1213 MIB does not have VLAN interfaces and does not perform counters accumulation.
