Liang Fang 9073f7591e Leverage hw accelerator in image compression 
When trying to upload volume to glance as image, currently all the
format transformation is done by software and the performance is not
good.

Leverage hardware accelerator to do the image compression, so as to
offload CPU, release CPU to do more common and complex thing.
Professional hardware accelerator will get better performance and
shorter conversion time than software solution. Currently hardware
accelerator is getting more popular and some are integrated in server
chipset by default.

This patch includes:

1. Uses the new image container_format 'compressed' introduced by Glance
in the Train release

2. Implemented a simple framework: if there's an accelerator detected in
system, then try to use it

3. Supported Intel QAT as one of the accelerator

4. Add command filter for command 'qzip' and 'gzip' in rootwrap

5. New configuration option 'allow_compression_on_image_upload' and
'compression_format' added

6. Releasenote added
