Implement "Issue pickers" functionality like Data Center#93

As an Jira Admin,
I want to have the functionality related to the issue picker of the Data Center in Cloud, so we can migrate to Cloud from DC

• Issue pickers customfields
• The JQL function of “issueFunction in issuePickerField“ https://docs.adaptavist.com/sr4js/latest/features/jql-functions/included-jql-functions/issue-links
• Issue pickers, behaviours to set the “currentJql” configParam
  issuepickerCf.setConfigParam(‘currentJql’, myjJql)

Hi @Jmgarrido and those who upvoted this request! We are taking this and other Scripted Fields related suggestions into consideration as we continue to prioritise our backlog. We’ll keep you posted!
