fix(dnsoverudp): allow to cancel async round trip immediately (#763)
To this end, we need to refactor the implementation to give the
DNSOverUDPChannel owenership over the net.Conn.

Once this happens, DNSOverUDPChannel.Close closes the conn.

When the conn is closed, the background goroutine will terminate
immediately because any blocking I/O operation will be immediately
unblocked and return net.ErrClosed.
