Symptom:
1. When iSCSI Target Interface is set to "Auto", users need to manually set "Initiator IP Address Policy" to 
"Default (DHCP)" (currently GUI does not set it automatically). If users forgot to change it, backend will through an error when trying to change it later and prevent users to made change to "Default (DHCP)".
2. When setting iSCSI Boot Parameters, if there is a change for "Authentication Profile" with other changes, "Save" button will be re-enabled again after first save (only authentication profile will be saved), re-click the button again will save "Initiator Name" and Target settings. The button now is disabled but "IQN Pool Name" setting is not save. 
3. GUI at first doesn't let empty DHCP Vendor ID to be saved but if user types something in the DHCP Vendor ID box and deletes it, User can save the empty DHCP Vendor ID

Conditions:
It happens from UCSC 2+ to Auburn releases.
