go-libp2p-kad-dht: #236 makes this library unusable for `go get` projects

#236

Failing build for github.com/prysmaticlabs/prysm: https://api.travis-ci.com/v3/job/177080918/log.txt

How are users supposed to use this library with go get?

Looks like this is the one of the offending code:

https://github.com/libp2p/go-libp2p-kad-dht/blob/f05ddbf46b89295d1eace1c435c24f395a52f36d/dht.go#L11-L13

Where github.com/libp2p/go-libp2p-kad-dht/v5/providers does not exist. Looking in this repository and godocs, this directory doesn’t exist.
