Breaking Changes

• The libp2p.MultiaddrResolver option now takes an interface rather than a
  specific pointer. This decouples the resolver from a specific implementation
  and also defines a better interface that is aware of bounds.
  • The swarm exports a new type ResolverFromMaDNS that implements this interface from a *madns.Resolver. The one line diff is essentially:

  -libp2p.MultiaddrResolver(rslv)
  +libp2p.MultiaddrResolver(swarm.ResolverFromMaDNS{Resolver: rslv})

✅ Release Checklist

• Stage 0 - Finishing Touches
  • Go through relevant libp2p repos looking for unreleased changes that should make it into the release. If you find any, cut releases.
