dparalen 7e72ceffd1 Terminal state transitions in transactions 
Multiple spots were not using DB transactions when processing the terminal
state transitions (error, abort, finish, timeout). The pattern looked like
this:

    node_info.fsm_event(istate.Events.error)
    # more code
    node_info.finished(error='Oops!')

which led to brief periodes of state inconsistency of NodeInfo records in
the DB.

This patch refactors the NodeInfo.finished() method to require a terminal state
transition to perform as part of the NodeInfo state update:

   NodeInfo().finished(istate.Events.finish)
   NodeInfo().finished(istate.Events.abort, 'Canceled by operator')

This patch also introduces a new state: aborting to allow the inspector to
try call power-off the node before marking the introspection aborted.

There's a new DB migration since the new state implies a schema change too
(Enum).

Hardware introspection for OpenStack Bare Metal

Introduction

image

This is an auxiliary service for discovering hardware properties for a node managed by Ironic. Hardware introspection or hardware properties discovery is a process of getting hardware parameters required for scheduling from a bare metal node, given it's power management credentials (e.g. IPMI address, user name and password).

Note

ironic-inspector was called ironic-discoverd before version 2.0.0.
