   To use this step, you need an access to running [Open STF](https://openstf.io/) instance with at least 1 device connected.
   [Access token](https://github.com/openstf/stf/blob/master/doc/API.md#authentication) and ADB keys has to be set up using STF web UI.
   Typical workflow:
-  1. App compilation e.g. using Gradle Runner step
-  2. Open STF Connect (this step)
-  3. Android instrumention and/or UI tests e.g. using Gradle Unit Test step
-  4. Open STF Disconnect step with `is_always_run: true` (to stop using remote devices)
