On client side, for phase-1 of quench we will implement the following -

1) Client will honor list of services returned by the server.
2) Clients will apply the services returned by discovery gracefully.
3) If Discovery returns an empty list, the client will continue using the older connections.
4) If Discovery returns a smaller list of services, client will use the shorter list and continue using
     services from older list - i,e client will not CLEANUP the additional existing connections.
5) Note, clients on discovering services DOWN, will wait fot atleast heartbeat detect DOWN
     time i.e 3 keepalives (= 15 secs) before re-subscribing to get new set of services.

Vrouter changes to honor the new set of services sent by discovery irrespective of the
current state of connection to control-node or dns-server.

a) Do not send update connection info after deleting the connection info, this results in the
library creating a new connection info ds. (not_ready event is triggered after connection
info is deleted)

b) Do not remove stale entries as we want to keep working with older entries in case the
discovery server returns a smaller list of servers or empty server list.
