User profiles should be removable to allow a default profile to be applied

Current SItuation

• The change request JOC-477 implements the feature "Add default profile".
• If a user deletes and recreates an account, then the default profile configured in joc.properties does not take effect.
• The reason for this behavior is the fact that the user profile that is stored in the database currently is not removed when an account is deleted. This applies
  • to local accounts that are managed with shiro.ini and
  • this applies to accounts that are authenticated with LDAP servers. For such accounts no operation is available to remove the profile.

How to reproduce

• Configure default_profile_account = root in the joc.properties
• Login as the root and change any one setting in the profile
• Create a new user test_otrs
• Login as the user test_otrs, the changed setting from root's profile will be visible.
• Delete the user test_otrs and recreate it with the same username
• Login back in JOC with test_otrs user's credentials
• The test_otrs user profile will have all default settings.

Desired Behavior

• The functionality "Add default profile" should be effective when an account is deleted and recreated.
• A new view will be added to the JOC Cockpit Account Management that is available for administrators:
  • This view shows the list of all profiles (accounts and last access date).
  • The view offers
    • to remove individual profiles from the database by use of an action menu.
    • to remove all selected profiles from the database by use of a button "Remove Profile"
  • When removing profiles then any customizations created by the respective accounts will be removed.

Workaround

• If you have access to the Reporting database then you can delete the profile (e.g. of the user test_otrs) with
  SQL statement to delete profile 'test_otrs'

  delete from JOC_CONFIGURATIONS where "ACCOUNT"='test_otrs';
  commit;
