Description of problem:
Deleting a user appears to be a "last resort" or a clean-up step for users creating fake/useless accounts.
Disabling a user appears to be safer, and retains their history.
The Delete button on the user administration page should be hidden inside the user record, where the Enabled checkbox is.
The Enabled checkbox could be moved out to the user list as a toggle button.

Version-Release number of selected component (if applicable):
3.0

How reproducible:
Easy always

Steps to Reproduce:
1. Login as admin
2. Go to $server/zanata/admin/usermanager
  - Delete is here, but is an edge case
3. Select a user (Edit button)

Actual results:
Checkbox to enable / disable is here

Expected results:
The Delete edge case should be in the user edit, not the Dis/Enable case
