Setup SMAC on routed packets destined to virtual endpoints

All L3 Routed packets destined to virtual endpoints in the datacenter
managed by ODL do not carry a proper source-mac address in such frames
put out to virtual endpoints. With the fix all the packets destined to
virtual endpoints shall have gateway mac as source mac. If gateway mac
is not recoverable for the subnet on which the virtual endpoint resides,
then the connected mac address of that virtual endpoint will be used as
the source mac address.  Here the connected mac address represents the
mac-address on the tapxxx (or) the vhuxxx port on OVS Datapath for that
virtual endpoint.

VrfEntry yang model is used to represent the gateway source mac.

Sample Group Entry:
group_id=150001,type=all,bucket=actions=set_field:fa:16:3e:a1:4b:61->eth_src,set_field:fa:16:3e:21:b8:d3->eth_dst,load:0x300->NXM_NX_REG6[],resubmit(,220)
