Renames the role to upload-forge because you can actually
run your own Forge server if you want.
This patch adds a custom module to the upload-forge
role that provides the "forge_upload" module.
This directly interacts with the a Forge API to upload the
module. The only dependency is that the python requests
module is installed.
