As a GitLab instance admin, you can set up Jira development panel integration of all groups

Description

• As a GitLab instance admin, you can set up Jira development panel integration of all groups, including the case if you are not a member of one of those groups.
• That is, Jira development panel integration (in particular, able to see all GitLab repos via the dev panel in Jira) is possible for all these cases.

Original description

### Summary

When setting up the JIRA DVCS integration as the root user in GitLab, you are unable to access projects for a group that the root user is not a member of. The DVCS account is created in JIRA, but no projects will be added.

Steps to reproduce

1. Create group that the root user is not a member of.
2. Set up JIRA DVCS integration, authorizing as the root user in GitLab
3. In JIRA, set up DVCS account for group that root is not a member of.

What is the current bug behavior?

Unable to access GitLab repositories in JIRA when root is not a member of the group.

What is the expected correct behavior?

All projects should be added in JIRA for a group the root user is not a member of.

Customer ticket: https://gitlab.zendesk.com/agent/tickets/110163 (internal use) I was able to reproduce this on my test instance. Once I added the root user to the group, I was able to update the DVCS account in JIRA and see the projects.
