Switch SPARC provisioning modes

SPARC servers can be provisioned using OS Build Plans.

To ease the switch between modes and the dhcpd.conf configuration, a script was created:

/opt/opsware/boot/jumpstart-sparc-ogfs/tools/switch_OSS-OSBP.sh

When run, it will print the current provisioning mode for SPARC servers and ask for your confirmation before doing the actual changes in order to switch it. If you continue, the script will backup the dhcpd.conf file, do the changes and restart the dhcpd service.
