Skip workflows if executed processes are not in the list of processes / process levels

[m-mohr]

Workflow tests should only run if executed processes are in the list of processes / process levels, otherwise they should be skipped.

See fixtures processes and process_levels.

How do we do with load_stac? If not present I should try to use an openEO collection with which name?

[m-mohr]

In other tests I simply skipped tests that can't be fulfilled by the backend due to missing processes, unless a given processing level requires the process (then it should be reported as error).

But then it would be impossible to test the SentinelHub back-end or any other back-end not yet supporting load_stac, but able to index the sample collection, despite load_stac not being a process of the L1.

@m-mohr a couple of things:

1. Are the conformance level public already? I know they are here, but it's a private repo: https://github.com/openEOPlatform/architecture-docs/blob/master/interface/processes/results/profiles.md. Edit: nevermind, I found them, you mention the page in your processes README. https://openeo.org/documentation/1.0/developers/profiles/processes.html
2. Should we also document the tests that are skipped due to a missing process? Skipping them directly would not be so informative imho.

[m-mohr]

You can of course also make it configurable to provide a collection ID, but if neither a collection ID nor load_stac is abailable, skip it with a notice. I also do it that way in my tests, feel free to check it for examples.

1. Yes, published on https://openeo.org/documentation/1.0/developers/profiles/api.html and https://openeo.org/documentation/1.0/developers/profiles/processes.html
2. I skip them with a message, see my examples. Show them with the -rs flag in the CLI.
