This is a PoC of a resource agent that calls masakari APIs if
instance's host failure is occurred.
The purposes of this patch is below:
- Show how to call the masakari APIs from nova-host-alerter.
- Indicate the implementation of the masakari driver.
This PoC is based on a idea called as "Modular architecture".
But "Modular architecture" is not implemented yet. So this is just
a PoC.
On this patch, we assumed that nova-host-alerter has 'driver' param
in the primitive definition, and that 'masakari' or 'mistral' is
set for the driver param.
And we plan to place masakari_driver.py and masakari_driver.conf
in the same directory as nova-host-alerter.
