protocol/client: propagte GF_EVENT_CHILD_PING only for connections to brick
Two reasons:
* ping responses from glusterd may not be relevant for Halo
replication. Instead, it might be interested in only knowing whether
the brick itself is responsive.
* When a brick is killed, propagating GF_EVENT_CHILD_PING of ping
response from glusterd results in GF_EVENT_DISCONNECT spuriously
propagated to parent xlators. These DISCONNECT events are from the
connections client establishes with glusterd as part of its
reconnect logic. Without GF_EVENT_CHILD_PING, the last event
propagated to parent xlators would be the first DISCONNECT event
from brick and hence subsequent DISCONNECTS to glusterd are not
propagated as protocol/client prevents same event being propagated
to parent xlators consecutively. propagating GF_EVENT_CHILD_PING for
ping responses from glusterd would change the last_sent_event to
GF_EVENT_CHILD_PING and hence protocol/client cannot prevent
subsequent DISCONNECT events
