Changes for FR #897
Support For DHCP IP Reservation
Main:
- added If statement to skipp SetStaticIPv4 if dhcpRserv=1
getStaticIPv4Settings:
- Added Whiptail asking if user wants to use DHCP reservation Settings, this will add dhcpReserv and
skip setStaticIPv4 while still logging everything.
ConfigExample files:
- Added staticReserv=0 to config examples. so it can be used with Unattended install
* 0 means static ip will be setup.
* 1 means DHCP Reservation will be used and no chage will be made to the interfaces
