[LU-14107] Keep peer representation consistent across LNet and the LNDs

Related — Mon, 2 Nov 2020 19:55:15 +0000

LNet and the LNDs maintain their own representations of peers and these may get out of sync.

For example, if peer is deleted from LNet (e.g. by running "lnetctl peer del"), the LND still retains the peer and associated connections (easily verified by running "netstat" or the IB equivalent). On the other hand, if peer is brought down and the connections are broken in the LND, LNet still retains the peer.

There are issues with both of these scenarios. The purpose of this task is to come up with a way to make LNet and the LNDs network views more coherent to help avoid these issues.
