[Libvirt-cim] [PATCH 0 of 5] Migrate from scheam 2.16 to 2.21

[Kaitlin Rupert]

This patchset provides the set of changes needed to upgrade to scheam 2.21.

The easiest way to test this is to do the following:

1) make preuninstall
2) make uninstall
3) Recongifure your source tree to pick up the makefile changes
5) make 
6) make preinstall
7) Restart your CIMOM (to be sure to pick up the new schema)
8) make install
9) make postinstall

I've also testing this by uninstalling Pegasus / sfcb and removing the repository.  Then reinstalling Pegasus / sfcb and doing the steps above.
