Porter needs to learn about the nucypher network and ursulas in order to execute network functionality on behalf of Alice(#2666) and Bob (#2667).

Presumably, this makes Porter some sort of a Learner:

• Some analogies may be drawn from the status monitor "Crawler" - https://github.com/nucypher/nucypher-monitor/blob/main/monitor/crawler.py#L152
• Stubbed client functions to be used by eventual endpoints (functions to be actually implemented with associated endpoints in other issues) - this just provides the basic plumbing
