* Add method for injecting password into OS.

* Modify Ironic state machine as described in the state machine impact section

* Add AgentRescue driver (implements base.RescueInterface). This driver will

be mixed into the agent_ipmitool and agent_pyghmi drivers.

* Add AgentRescue driver (implements base.RescueInterface). This implementation
|

will be available only through hardware type. It would not be supported in
|

the classic drivers as they would be deprecated shortly.
|
||||
* For classic drivers rescue interface would be set to 'no-rescue' which would
|
||||
generate 'UnsupportedDriverExtension' exception when any methods of this
|
||||
interface are invoked.
|

* Add periodic task _check_rescue_timeouts to fail the rescue process if
|

it takes longer than rescue_callback_timeout seconds for the rescue ramdisk
|
||||
to come online.

Client (CLI) impact
|

-------------------

Support for the new verbs "rescue" and "unrescue" must be added to the client.

The OSC command line will require additional code to handle the new state.

New command line options ``rescue`` and ``unrescue`` would be added to

support rescue and unrescue operations.

None, because we defined the RescueInterface a long time ago.

Add a new method clean_up() for RescueInterface in base.py. This method would
|

perform any necessary clean up of the node upon RESCUEWAIT timeout/failure
|

or finishing rescue operation. Some of the cleaning tasks are removing rescue

password from the node. Ramdisk boot environment should be cleaned if

ironic is managing the ramdisk boot. It would have default implementation as

given below::

class RescueInterface(BaseInterface):

def clean_up(self, task):
