test cvmfs availability in pytests

[marco66colombo]

Description

This draft PR is intended to trigger the GitLab CI pipeline and verify that CVMFS is mounted in the GitLab jobs where tests are run.

This code is not meant to be merged into the main branch but is instead used to check the availability of CVMFS and Vivado in the containers where the CI test jobs are executed.

To determine whether CVMFS and Vivado are accessible in PyTests, the generate_ci_yaml.py file has been modified to run only one job with the necessary test cases, thus avoiding the execution of other time and resource-consuming tests.

test/pytest/test_cvmfs_mount.py has been added to specifically test CVMFS configuration and availability. This is the only file from which tests should run for this draft PR.
