`get_all_appointments` in docker for Mac and Windows

[sr-gi]

Given that a docker container cannot be run on Mac and Windows using network=host, requests to get_all_appointments are rejected by the tower.

get_all_appointemnts is an admin only command that is used to check the state of the tower and therefore, can only be called from localhost.

Not sure if it is worth finding an alternative solution to this. The admin can always log into the container to run this since it is not a command you'll use often. Also, #148 is being developed to get a way better report about the state of the tower, so it may be worth removing this command once it is merged.

get_all_appointments can now be called via docker exec since teos_cli is a command line tool.

However, RPCs cannot be called from the outside from the same exact reason as before. We will need to look into that.
