Ruby Loo 4f8b97dff6 Show transitions initiated by API requests 
This updates the state machine diagram and documentation to indicate
which transitions are initiated by API requests versus the ones that
are internally done by the conductor. Stable states are highlighted
a bit.

Ironic's State Machine

State Machine Diagram

The diagram below shows the provisioning states that an Ironic node goes through during the lifetime of a node. The diagram also depicts the events that transition the node to different states.

Stable states are highlighted with a thicker border. All transitions from stable states are initiated by API requests. There are a few other API-initiated-transitions that are possible from non-stable states. The events for these API-initiated transitions are indicated with '(via API)'. Internally, the conductor initiates the other transitions (depicted in gray).

Note

For more information about the states, see the specification located at ironic-state-machine.
