feat(github): support usage of gh-token for deployment from external env

In order to being able to push to github from CI (Travis for example), we should be able to provide a token to the cli, as `--gh-token=XYZ`. This modification allow to use this token in the destination url. This also allow user to push to another github repository if it uses a different `--gh-username` from the one used for the checkout.
