Flickering strategy change for the JIRA "Flickering Test" delimiter + FQN

Hi devs,

Right now we use the comma (’,’) as the delimiter in the “Flickering Test” custom field for flickers. However, we need to start using the full signature for a test (because there can be several test signatures), which can include commas, such as in:

org.xwiki.flamingo.test.docker.AllITs$NestedEditIT#saveAndFormManipulation{TestUtils, TestReference}

Thus, I’ve make changes in our pipeline to use the pipe delimiter char (’|’) instead and I’m fixing all open flickers in jira that had a list specified.
