[GH-#111] After adding a peer add his peers

[cheezus1]

closes #111

[cytadela8]

Hmm... I didn't know about #111. This conflicts with my work on #115.

[cytadela8]

I suggest, I will try to propose an overall solution to peer sync this evening.

[thepiwo]

Yeah maybe it is conflicting, but we need both issues solved. Could you integrate these changes in your work?

[cytadela8]

@thepiwo I will try to do that this evening, but at the moment I think this PR conflicts with my design choices. I will try to think how to make everything work this evening and probably I will propose some solution.

[cytadela8]

After analysing possibilities I took the test fix and max_peers limit from this code. Sadly most of this code conflicts with peer sync design I would like to introduce with #123. Sorry for not realizing the conflict earlier!

[thepiwo]

@cytadela8 so we merge this, prior to #123? Or do we ignore this?

[cytadela8]

@thepiwo We ignore this. I cherry-picked one commit and rewritten max_peers.

[thepiwo]

replaced with #123
