Adds peers rpc to the bitcoin command group

[sr-gi]

Adds a peers rpc that displays the peers of a given tank.

This is really useful to check connectivity against network graphs, and just as a general sense of who's connected to who.

e.g.

warnet bitcoin peers tank-0000

manual            tank-0004
manual            tank-0005
manual            tank-0006
manual            tank-0013
manual            tank-0014
manual            tank-0015
manual            tank-0019
manual            tank-0021
inbound           tank-0001
inbound           tank-0003
inbound           tank-0007
inbound           tank-0008
inbound           tank-0016

I'm not opposed to adding this but the bitcoin-cli table is also available via RPC:

(.venv) --> warnet bitcoin rpc tank-0000 -netinfo 4

To me, the QoL of this the tank name mapping for inbounds. If you'd like to stick with -netinfo instead, what about capturing the return and mapping the IPs to the tank names before displaying?
