swarm/: Provide additional default impls on NetworkBehaviour (#2150)

Browse Source 
Not all implementations of `NetworkBehaviour` need all callbacks.
We've have been adding new callbacks with default implementations
for a while now. There is no reason the initial ones cannot also
be defaulted, thus making it easier create new implementations.
