Update multiple validation result to ConnectivityService

Once a network is determined to have partial connectivity, it
cannot go back to full connectivity without a disconnect. This
is because NetworkMonitor can only communicate either
PARTIAL_CONNECTIVITY or VALID, but not both. Thus, multiple
validation results allow ConnectivityService to know the real
network status.
