automatic PXE and puppet-master installer for OpenStack - utils

OCI (OpenStack Cluster Installer) is a software to provision an OpenStack clusters automatically. This package installs a provisioning machine, which uses the below components:

 * a DHCP server (isc-dhcp-server)
 * a PXE boot server (tftp-hpa)
 * a web server (apache2)
 * a puppet-master

Once computers in the cluster boot for the first time, a Debian live system is served by OCI over PXE, to act as a discovery image. This live system then reports the hardware features back to OCI. Computers can then be installed with Debian from that live system, configured with a puppet-agent that will connect to the puppet-master of OCI. After Debian is installed, the server reboots, and OpenStack services are provisionned, depending on the server role in the cluster.

OCI is fully packaged in Debian, including all of the Puppet modules. After installing the OCI package and its dependencies, no other artificat needs to be installed on your provisioning server, meaning that if a local debian mirror is available, the OpenStack cluster installation can be done completely offline.

This package contains utilities that are going to be installed on the system of machines running in production. It contains programs like:

 * oci-report-status: reports once a machine has finished booting.
 * oci-first-boot: script that does the first puppet runs and setups puppet.
 * oci-build-cinder-volume-vg: create the LVM volume group for volume machines.
 * oci-build-nova-instances-vg: build a volume group for nova to use.
 * and many more like this...
