Work on ITest-2 Failures:
- I think the recent work for 1071330 which added caching and last-update
  logic around SystemSettings adversely affected the LDAP tests which
  where doing direct update of read-only system settings.  Adding a
  new inetrnal-only local SLSB for safely updating a read-only SystemSetting
  and refactoring test class to use it.
- Removed now-obsolete NamedQuery that supported the old test-class logic.

Work on ITest-2 Failures:
- More work around 1071330 which added caching and last-update
  logic around SystemSettings.  Adding an internal-only local SLSB
  method which allows write of readOnly system settings.  This is
  analogous to the one I added a few minutes ago for a single setting.
- Convert SynchronizationManagerbeanTest to use SystemSettings as opposed
  to the deprecated systemConfig API, and use the internal SLSB methods
  as needed.

 Itests still not resolving the correct dependencies. Another fix.
  - updated Abstract classes to consistently use the same properties
  - update plugin container itests to check before going to classpath.
