JIRA integration

This MR adds a new class CERNJira which can be used to create, edit issues in JIRA. It requires cern_sso from the lbaplocal lbapcommon package.

To-do:

• Linting, formatting, CI checks

• retest CERNJira.edit_issue and .create_issue

• use a CERNJira object to create a task at https://gitlab.cern.ch/lhcb-dpa/analysis-productions/LbAnalysisProductions/-/blob/eebf8cdee55e287e3967b06015c2ddd011d4ae24/src/LbAnalysisProductions/submission.py#L144-152

• emails from the inform: field are used to query for a matching JIRA user, then cc. and add them as watchers on the task

• Figure out how to configure / retrieve CERN usernames for liaisons
