untagged-471bd4176f544f6f9ef0: Fixes docker-tag and docker-push stages in travis-ci

* Sets dist/os to the defaults
* Does not check for branch is master and a tag since these will never be true
* Removes on: tags=true
* Removes deprecated: sudo: required
* Replaces deprecated `api_token` with `token`
* Uses unique names so travis doesn't warn
