Add support for test suites

[razvan]

Description

Jenkins should use the new --suite beku option to run test suites.

Acceptance

• nightly test run the nightly test suite which may be different per product/operator.
• The UI for custom tests has a new field that allows the user to enter a suite name. If nothing is entered, Jenkins runs the default test suite.
• There is an alternative script to scripts/run_tests.sh that can pass the --suite to beku.

Nightly suite added to operator:
