pull WIP fix for go-libp2p-kad-dht request goroutine bug

This pulls in libp2p/go-libp2p-kad-dht#730,
which hangs on a branch shortly after 0.12.2.

Essentially, this handles priority for requests a bit better,
and drops unimportant requests if they come in too fast.
This should prevent kad-dht from using tons of memory.

Updates #243.
