What is the current state of E2E Platform tests?

@raff @k.joseph @dkayiwa @ibacher I found this ticket today: https://issues.openmrs.org/browse/TRUNK-5196

Closed it because it’s old, vague, and a big chunk of work, but it raises a good point: What is the current state of our E2E platform testing? What did you end up setting up back in 2017 @raff?

Thanks for your help - this is an area of great interest so that we can grow our confidence in our releases moving forward.
