This role uses the system-config:install_puppet.sh script to first
install puppet on the wheel-builder host, and then uses
puppet-kerberos/puppet-openafs to bring up the AFS environment.
This is replaced with ansible roles to do the same AFS bring-up. A
new "openafs-client" playbook is added to configure this for the infra
environment. The wheel-building base job is reworked to use this.
