Sharding test runs with ordered execution supported

[ahervieuxgirard]

Use case

Since the sharding options are --shard-split or --shard-all, being able to combine execution order and running folders with multiple devices would be a great improvement

Proposal

Should be able to run folders while sharding execution using config.yaml file on any types of devices.

Anything else?

More context when trying to achieve this right now we have this message :

Cannot run sharded tests with sequential execution

The stack trace was:
java.lang.IllegalStateException: Cannot run sharded tests with sequential execution
