Clean up configure_containers.sh script

Remove packages that are apparently not being used in heat-agents
container and depend on python-heat-agent-puppet rather than a list of
individual packages.

Make it clear which packages are runtime dependencies and which are
only required for their configuration files. Packages are now sorted
alphabetically.
