Debug instance for the gossipsub behaviour (#1673)

Browse Source 
* Add debug instances for MessageCache and GossipSub behaviour

* Manual impl of Debug for GossipsubMessage

* Add pretty printing of protocol_id in debug

* Use hex_fmt instead of hex

* Inline StringOrBytes helper struct

Since it is used only once here

* Limit data of gossipsub msg to 20 bytes

Otherwise they might become very large and useless for debugging
