Give the DHCP server its own seperate roles.

This splits provisioner-server into
provisioner-server, which still handles TFTP and the provisioner web server.
provisioner-dhcp-server, which brings up DHCP and configured default PXE settings.
provisioner-dhcp-database, which hooks into the node lifecycle to handle per-node PXE and DHCP.

Allow the provisioner to install Ubuntu 12.04

These are the bare minimums to install Ubuntu 12.04 on a non-admin node.
This should be sufficient to enable us to start working on porting over
workload barclamps.
