Adds a ``ramdisk`` deploy interface for deployments that wish to network
boot to a ramdisk, as opposed to perform a complete
traditional deployment to a physical media. This may be useful in
scientific use cases or where ephemeral baremetal machines are desired.
The ``ramdisk`` deploy interface is intended for advanced users and has
some particular operational caveats that the users should be aware of
prior to use, such as network access list requirements and configuration
drive architectural restrictions and the inability to leverage
configuration drives.
