Allow custom ip address and adapter type

[brunnels]

Could you please add parameters to set the network connection type for the VM and also the ip address or hostname to utilize?

On my dev box the firewall is locked down on all adapters so I can't ping or ssh to the NAT device. I can trick it into finishing now by changing the VM to bridged and then manually set the ip address in the dhcp leases file.

Our dhcp server will always create a dns entry based on the hostname so I can use that in the start.sh if the additional driver parameters were added.
