Set and export KUBECONFIG in root user .bash_profile

- roles/base_os: Without this, the root user would need to manually configure
  this variable before attempting to run any osc commands
- roles/base_os: Cleanup the firewall service definition and only pause when
  the service
  state changes.
- roles/openshift_master: use Akram's suggestion of simplifying the firewall
  config
- roles/openshift_master: explicitly disable previously exposed ports that are
  no longer exposed (8080/tcp I'm looking at you).
