Configurage no_compression_image_types
Ability to configure image types for which transfer will not use compression when migrating instance.
This value was previously hardcoded to disable compression for qcow2 only.
In real world scenario, compressing raw images during migration makes it
CPU-bound (single core) instead of network-bound, slowing it down to about 8 mbps in tests.
Disabling compression for RAW naturally allows to saturate network link without saturating CPU core.
Operators may prefer to disable compression for raw images.
