Lucas Alvares Gomes ea1b012e93 Periodically checks for nodes being cleaned
This patch is adding a periodic task to check for nodes waiting for the
ramdisk callback when cleaning is being executed.

A new configuration option called "clean_callback_timeout" was added,
its value is the number of seconds that the Ironic conductor will wait
for the ramdisk to doing the cleaning to contact Ironic back. Defaults
to 1800.
