Change RoutingInstances' UVE key to virtual-network

[Ananth Suryanarayana]

Normally, a routing-instance name maps 1:1 to virtual-network. However for service-chains, 2 more routing-instances are created with auto-generated names. But the auto-generated ones also belong to a parent virtual-network. All UVEs and logs generated must use the parent virtual-network as the key (name) for easier debug-ability.

Update RoutingInstance table stats key to virtual_network name

o Change key from ObjectRoutingInstance to ObjectVNTable for easier debug-ability
o Always send table-stats. Sandesh library takes care of pruning stats that did
not change from last send.
o Flatten table stats list to the list of 4 families that each instance carries
and use the instance-name as the key value for the stats map
o Maintain a map of virtual-network names to a set of routing-instance names
and update this during instance creation/deletion/update
o When an instance is deleted, send explicit uve delete with table stats marked
as deleted
o When all instances under a virutal-network are deleted, delete the entire
RoutingInstanceStats which is now keyed by the name of the associated
virtual-network
o Normally, virtual-network names matches with routing-instance names. However,
for service-chains, multiple (left and right) routing-instances are created
in addition by schema-transformer. For all such instances, the stats uves are
now sent based on the associated virtual-network name as the key
o Move table stats sandesh file and its processing code to routing-instance
directory. The stats are table specific and applies to routes leanred over
both bgp and xmpp
