mDNS is used by wifi p2p in many places. However,
MdnsSocketProvider does not monitor changes to the wifi p2p
connection to get the names of the available wifi p2p interfaces.
This prevents mDNS from registering or discovering services on
the wifi p2p interfaces. Therefore, listen to the wifi p2p change
intent to know the available interfaces and status changes that
can be used by mDNS.
