GitLab Jira Integration - Users don't exist in GitLab but they do in JIRA
Proposal
The ability to keep original users in JIRA(Such as author or people that have left) to the GitLab JIRA integration even if they don't exist in GitLab but they do in JIRA.
Customers that want to leverage the integration can only do so if the user exists in GitLab. But the user might not always exist in GitLab if they've left the company or something.
