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
