=> Modified VyattaConfig.pm function 'returnOrigValues()' to return empty array when no value is configured

=> Modified VyattaConfigLoad.pm to give a higher ranking to 'system host-name' than 'interface' so that during boot-up
   if host is using dhcp client to get an ip for an interface, it can send the host-name if configured
=> Modified vyatta-interfaces.pl:
   1. to request only for dhcp options 'subnet-nask', 'broadcast address', 'routers', 'domain-name-servers'
      when an interface is configured to get an ip using dhcp.
   2. ask for a domain-name only if domain-name is not configured in our CLI
   3. do not request dhcp options: 'time-offset', 'interface-mtu' and 'host-name' that were being requested before
   4. Update /etc/resolv.conf to remove domain-name and name-server options received from dhcp server for the
      particular interface that releases dhcp lease either from op-mode or cfg-mode
