Added code changes related to Layer 2 Forwarding Enhancements:

Changes are as mentioned in the HLD.

Added support for per port, per vlan and per port-vlan fdb flush.

Added fdb reference count in port and vlan in portsorch to keep track of number of fdb entries learnt on the port or vlan and delete the bridge port or vlan when the fdb count in 0.

Added new data structure in portsorch for mapping between OID and vlan/port/bridge port.

Moved SAI Redis fdb handling to fdborch to have both the fdborch and sai redis reference count in sync

Changed default vlan state in kernel to Down and make it Up only when first port/lag in the vlan is oper up. Make vlan Down when last vlan member goes oper down. Orchagent sends notification to vlanmgr when first/last vlan member goes up/down.

Added support for add/remove vlan 1 from config. Also, if port is member of vlan 1, will not remove it from vlan 1 after adding port to bridge in kernel.

Added support for static fdb config and fdb aging time config.

When a port is removed from VLAN, static fdb are flushed in HW and in fdborch, static fdb are added back to savedFdbEntries.

Added port channel port oid to name mapping in COUNTERS_PORT_NAME_MAP table so
that a given portchannel port oid will give port channel name

Made fix to add add portchannel port oid to name mapping when addLag is done
from portsorch. similarly removed the mapping when removeLag is done

Issue:

fdbshow does not show the portchannel name

Fix:

1.Added port channel port oid to name mapping in COUNTERS_PORT_NAME_MAP table so
that a given portchannel port oid will give port channel name

2. made fix to add add portchannel port oid to name mapping when addLag is done
from portsorch. similarly removed the mapping when removeLag is done

With the change there were compile errors related to some snmp scripts. I am yet to fix those. Will send an update by next week.

@anilkpandey , this PR is pretty big and few other PRs are dependent on parts of your changes. Is it possible to split the PR based on functionality to make reviewing easy and merge those to unblock dependent PRs?

…g DB (sonic-net#885)

Fix is_mgmt_vrf_enabled for the case where MGMT_VRF_CONFIG is not at all in the config DB.
This is the case where mgmt vrf is never configured. The function throws error at
File "/usr/lib/python2.7/dist-packages/show/main.py", line 651, in is_mgmt_vrf_enabled
mvrf_dict = json.loads(p.stdout.read())
Two show commands uses is_mgmt_vrf_enabled. "show mgmt-vrf" and "show ntp"
Both commands throw error if mgmt vrf is never configured
