Add introspect option to display vrouter object limits

[Naveen N]

VRouter takes modules parameters specifying number of label,
vrf route entries, mirror entries and next hops, agent should read
them and display it in agent introspect

* Read vrouter object limits from vrouter kernel module

1> VRouter has a object vrouter_ops which specifies limit
for individual object entries, changes are made to read
the same and display it using agent introspect.
2> Removed unnecessary index table operation in ksync for
mpls and vxlan object.
3> MPLS label space is dynamically allocated based on number
of VN vrouter supports. If label space is smaller then
4k label are reserved for VM interfaces and remaining label
gets equally split between 2 control nodes
Test case to check for multicast label algorithm
Closes-bug:#1456582
