Validator connection display

[DimitrisSar]

New feature request (not very important since you can't do much with this info): Add your current connection info to the validator
(gRPC over http/2 on outbound tcp/8080). Include: IP Address + Port and P2P address (67.211.223.5:8080, 112vvCWKx3s3JrHqxan4fAqNAoezsNXAGyFvZchZmV6mCfwmMcvA) from example below:

Also: not much info you can extract from the api on https://api.helium.io/v1/validators/112vvCWKx3s3JrHqxan4fAqNAoezsNXAGyFvZchZmV6mCfwmMcvA
https://explorer.helium.com/validators/112vvCWKx3s3JrHqxan4fAqNAoezsNXAGyFvZchZmV6mCfwmMcvA/activity

Example log contents to be processed:

The challenge will be to detect the current validator connection. In theory, it may change over time (after initial boot up of the miner)
