Add back nodeInfo, peerLimit and requestPacket fields to _peerSelectForRequest function - Closes #4142

[jondubois]

What was the problem?

• Some useful fields were removed from the custom selection function which limits the ability of the P2P library to do advanced routing of requests.
• There was an issue with the integration test related to peer eviction which made it brittle because the peers would not be started sequentially as was intended.

How did I solve it?

• Added back missing fields when calling the selectForRequest function.
• Fixed the integration test case so that each peer would wait one after another. Also, made each successive node point to the previous node instead of the next one (since the next one hasn't launched yet).

How to manually test it?

npm test
