test(e2e): add gitlab integration for test suite

Change the e2e tests to just run smoke tests in the MR pipelines, also added the option to trigger a whole run manual. Additionally, we run also the full set in a nightly run at 3:30 and upload the outcome to testrail, to get a proper test report.

The script is used to modify the testsuite names, to not have duplicate section wich is not handlebar by testrail.
