[ci] Move CSCS tests and configuration out of this repo

[vkarak]

The CSCS tests and the CSCS site-specific configuration have been moved to https://github.com/eth-cscs/cscs-reframe-tests.

There are still a couple of subtasks that need to be addressed before we merge this PR (see #2511 for more details).

Addresses #2511.

Is config/cscs-ci.py on the repo left on purpose?

[vkarak]

Is config/cscs-ci.py on the repo left on purpose?

Yes, because it's needed for the CSCS CI that tests the scheduler backends.

This is not necessary for this PR but since I saw that you changed the links to reframe-hpc, I think we also need to change the repo to reframe-hpc in the following files:

• .pep8speaks.yml
• CONTRIBUTING.md
• setup.cfg
• ci-scripts/deploy.sh
• docs/conf.py
• hpctestlib/microbenchmarks/gpu/gpu_burn.py
• reframe/frontend/cli.py
• reframe/schemas/config.json
• reframe/schemas/runreport.json
• reframe/utility/osext.py
• unittests/test_config.py
• unittests/test_utility.py

There are links to the contributing guidelines, to old issues etc..

[vkarak]

@ekouts That's a valid observation. I will fix those links.
