#22178: Reduce user_meta bloat for super admin users

   Status:  new             |   Priority:  normal
Milestone:  Future Release  |  Component:  Users
  Version:  3.4.2           |   Severity:  normal
 Keywords:                  |
----------------------------+--------------------------
 Super admins have {$blog_id}_user-settings, {$blog_id}_user-settings-time,
 and {$blog_id}_dashboard_quick_press_last_post_id usermeta entries added
 for every dashboard they visit, regardless of whether they are a user on
 the blog or not. The end result is that some super admins have many
 thousands of usermeta entries and a user object possibly over 1MB.  We
 have seen several in the 800k range containing these entries for over 300
 blogs.
