Julia Kreger c4e3100d5c Add hold steps
* Updates API version to 1.85 to permit an ``unhold`` verb
* Adds the ``deploy hold`` and ``clean hold`` provision states
  to the internal state machine.
* Adds on documentation on steps to help provide greater clarity
  to Ironic's users on how to utilize steps. It should be noted
  this documentation also includes the power state reserved step
  names from the DPU functionality patch.
* Fixes the state machine diagram. Changes type to PNG as SVG
  rendering is broken due to python libraries utilized for SVG
  generation which do not work on more recent Python versions.
