Allow JIRA Service Desk customers to access JIRA System Dashboard

Some teams would like their System Dashboard to be accessible publicly too allow users to see what items are being worked on, review the roadmap, and vote/comment on items.

Non-logged in users are able to access the System Dashboard without issues however once a Service Desk customer logs in, they're redirected to the Customer Portal and that is all they can access. This feature request is asking to allow logged in Service Desk customers to be able to view the JIRA System Dashboard instead of being redirected to the Customer Portal like they are currently.
