Completely change (and temporarily break) the relay bootstrapping script:
  * use a salt masterless method, where the bash script only installs and sets whats needed for the permanent salt-minion to run
  * reason for this: should make more maintainable and coherent things installed on minions since we will use same SLS files for bootstrap and when under authority of the master
  * we will use a temporary minion configuration file for the bootstrap where the bash script puts the specific info (ID, master hidden service, role)
  * the permanent minion configuration file will include those grains through the masterless execution
