Cucumber sharding support

[Foso]

Hello, we are using Green Coffee for our Android UI Tests running on Firebase Testlab with Flank. There, sharding is possible. Now we want to switch to cucumber-android where sharding is not possible using Flank. We are interested in contributing cucumber support for Flank, but we don`t know where to start. Can you give us a hint where we should look first and how we can start?

@Foso Ping me on the firebase test lab slack in #flank, I'm happy to share some ideas about how to approach this. Cucumber is primarily a test discovery challenge. If you know all the cucumber tests in advance, then flank will be able to run them.
