More IPFS interop - Githubissues

Further improves on our IPFS interoperability [#78]:

Sets the ClientVersion to identify our nodes through the /ipfs/identify protocol; new in libp2p-4.3.1
Integrates the libp2p PingService, so that nodes can ping/pong using the ipfs protocol and deprecates the /mediachain/node/ping protocol
New net api hooks
- /net/ping/{peerId} to ping using the ping service
- /net/identify/{peerId} for dumping the information collected for a peer by the libp2p IdentifyService

Examples:

$ mcclient id QmSbgwkKxtrBFDoGGwoKqH7soYiL64xpMK5oEYdiRnQGJp
Peer ID: QmSbgwkKxtrBFDoGGwoKqH7soYiL64xpMK5oEYdiRnQGJp
Publisher ID: 4XTTMGkYEx5trQX5VV32S82gguRMtVFQL5UDnZNHzyNEHKBeZ
Info: Mediachain Labs test node
