Putting Docker Login password (base64 encoded) into forge.yaml is NO BUENO

[plombardi89]

I just committed my Docker Hub password to source control (in forge.yaml). Thankfully it's not a public repository and I can delete the source tree but that's really really bad.

This file shouldn't ever need to be committed to github. It only contains global configuration (all service specific configuration is in service.yaml). I've added a big warning into the generated file that it contains secrets and that it should not be checked into github.
