Check if unclosed issues are still associated to released version

[tmortagne]

Right now when using release-jira-version goal, any unclosed issue associated to the released version end up associated to a released version which does not make much sense. In such a case the UI is asking what to do with those issues (remove the "fix for", move to another version, etc).

It would be great is the plugin was asking the same question than the UI when you release a version with release-jira-version when you have unclosed issues associated to it. Or at least provide some option to indicate what to do in this case.
