Refactored upgrade framework into base and server upgrade.

The upgrade framework has been split into base and server upgrade
frameworks since they will be run automatically by different RPM
packages during upgrade. The base upgrade framework will upgrade
the system configuration. The server upgrade framework will upgrade
the instances and subsystems.
