This step involves creating a junction object that will provide the linkages between Opportunity and ZIssue. This object establishes Master-Detail relationship between Opportunity (or another Salesforce object to be integrated with JIRA) and one or more Jira Issue(s).
A junction object is needed for each object that is to be integrated with Jira issue.
Once created, this junction object will also represent inverse Master-Detail relationships with Opportunity and ZIssue (Jira Issue), These will be defined in subsequent steps.
