Allow admins to to be added by default on private filters

Currently for private filters admins cannot View or Edit filters thus cannot see the boards associated
Requirement is to provide a functionality so that admins or admin groups can be added to the private filters by default.

Workaround

A site admin can go to the Manage filters system page and take ownership of any filter:
<your site name>.atlassian.net/secure/admin/filters/ViewSharedFilters.jspa

Once that's done they can manage the filter and its subscriptions themselves.
