swarm/network: Revised depth and health for Kademlia (#18354)

Browse Source 
* swarm/network: Revised depth calculation with tests

* swarm/network: WIP remove redundant "full" function

* swarm/network: WIP peerpot refactor

* swarm/network: Make test methods submethod of peerpot and embed kad

* swarm/network: Remove commented out code

* swarm/network: Rename health test functions

* swarm/network: Too many n's

* swarm/network: Change hive Healthy func to accept addresses

* swarm/network: Add Healthy proxy method for api in hive

* swarm/network: Skip failing test out of scope for PR

* swarm/network: Skip all tests dependent on SuggestPeers

* swarm/network: Remove commented code and useless kad Pof member

* swarm/network: Remove more unused code, add counter on depth test errors

* swarm/network: WIP Create Healthy assertion tests

* swarm/network: Roll back health related methods receiver change

* swarm/network: Hardwire network minproxbinsize in swarm sim

* swarm/network: Rework Health test to strict

Pending add test for saturation
And add test for as many as possible up to saturation

* swarm/network: Skip discovery tests (dependent on SuggestPeer)

* swarm/network: Remove useless minProxBinSize in stream

* swarm/network: Remove unnecessary testing.T param to assert health

* swarm/network: Implement t.Helper() in checkHealth

* swarm/network: Rename check back to assert now that we have helper magic

* swarm/network: Revert WaitTillHealthy change (deferred to nxt PR)

* swarm/network: Kademlia tests GotNN => ConnectNN

* swarm/network: Renames and comments

* swarm/network: Add comments
