Alan Norbauer 193b357a0c Add zerotier-cli info output to Docker logs
When I first bring up the container, I want to know I'm approving the join request for the right node. I can get the node's ZT address by manually executing `zerotier-cli info` in the node (e.g. with `docker-compose exec zerotier zerotier-cli info`) but just having it in the logs to start with is very convenient.
