[services] Tunnelbroker - Move init logging to the global tools

Summary: We want to use glog in other services, not only tunnelbroker. Therefore, I think we should move initializing function to the global tools so it can be accessed from the blob and the backup as well.

Test Plan:

cd services
yarn run-tunnelbroker-in-sandbox

Tunnelbroker builds without problems.
