* feat: add uPnP nat manager
Adds a really basic nat manager that attempts to use UPnP to punch
a hole through your router for any IPV4 tcp addresses you have
configured.
Adds any configured addresses to the node's observed addresses list
and adds observed addresses to `libp2p.multiaddrs` so we exchange
them with peers when performing `identify` and people can dial you.
Adds configuration options under `config.nat`
Hole punching is async to not affect start up time.

BREAKING CHANGE: all API methods with peer-info parameters or return values were changed. You can check the API.md document, in order to check the new values to use
When connecting to go-IPFS from a webworker, the stream opened by
the ping protocol is never closed.
The change here uses `take` to only receive one buffer from the
remote node before closing the stream.
