Allow creating and managing versions for Leads

Summary

Currently there is the possibility in the Config Mgmt addon to *give the "Leads" also the permission to manage versions. *However, we currently need an additional addon to make it work.
Iff CMTK offers this UI control, this feature should work without any additional addon.

Current situation:

The default Jira permission to create and manage versions (under releases) is mapped to role "Project Admin", which means only few people can create and manage new versions.
In the CMTK we are working with component versions and bundles (both are just a "jira version" in the background). In the addon you can manage the component versions as well as the admins or the leads. Unfortunately, this can not create new versions because in the background again the "Admin right" for the normal Jira releases is necessary.
That's why we currently also need the addon "Version Manager" which allows us for individual users to enable the generation of versions without admin rights.

Feature Request:

If the config in CMTK is set correctly and you allow leads to manage versions, the 3-points-menu for creating a "jira-version" for these leads should also be usable (see screenshot).

Currently the respective lead does not have these 3 points with the possibility "Create New Version" etc. unfortunately.
