This step connects to Google Play and check if there is a release in production with an in progress rollout. If found, it increases it to the next rollout percentage [2%, 5%, 10%, 20%, 50%, 100%]
The step makes use of the python library and Edits Api from Google Play. It downloads the info from the production track, and looks if any release in there has a 'userFraction' property defined. In case it has, and it is between 0 and 1, then it just modifies it to the next step, or completes the release if next is 100%
