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.
