[Ovirt-devel] [PATCH node] Creates a standalone mode entry point script.

NOTE: This is for feedback and testing, and requires the patch for
node-image to reintroduce hal-device.
The script will execute only when the node is booted without the support of
a server suite. If it determines that the node is running in standalone mode,
it will then kick over to a node setup script.
This iteration defines the general flow for the standalone mode's firstboot
use case. When the node boots and determines it's in standalone mode, it
goes through the following steps:
1. Prompt for an administrator password
2. Prompt the user to configure disk storage
3. Prompt the user to configure networking
4. Prompt the user to configure logging
The node then continues to boot normally.
