Refactor the long-hated users recipe into an HWRP

WIP :construction: 

* Refactor users recipe into an HWRP called ec11_users
* Throw out the old `createobjecttool` & `createorgtool` and use knife-opc instead which is MASSIVELY more reliable
  * This opens the door to a CS12 version
* Smarter logic to wait for HA master and then for erchef readyness, which helps this complete much faster
