This configures automated installation using the subiquity installer, as documented at https://ubuntu.com/server/docs/install/autoinstall-quickstart and other locations on the Internet. Installation uses the NFS export of /install, and configures the installer to use the nocloud-net datasource, creating a per-node directory containing the processed template file as the user-data file, and an empty meta-data file. Kernel and initrd files are pulled from the casper/ directory under the package dir. Unnecessary elements of the kernel command line have been removed in the subiquity installer path. Support has been added for selecting a subiquity specific default template, as well as an updated pre-install script and some minor POSIX shell compliance fixes for the getinstdisk script.
