Infinidat driver should use pool's compression setting when creating volumes

[Alexander Deiter]

Description: Infinidat driver should use pool's compression setting as default when creating volumes

Request from our customers and product manager:

1. We noticed that when volumes are created by Infinidat Cinder driver, they are created with compression disabled. The behavior should be changed to default to inherit from storage pool - we should only send compression_enabled in the InfiniBox creation request if the ``infinidat_use_compression`` option is actually set.

2. We may also remove support for pre-v3.0 InfiniBox systems that do not support compression. These versions are end of life and no longer supported for a long time.

Steps to reproduce:
* Create a pool in Infinidat storage with enabled compression option
* Configure Infinidat iSCSI or FC block storage backend
* Do not specify the ``infinidat_use_compression`` configuration option for the backend
* Create a new volume on top of the configured backend

Expected results:
The new volume was successfully created and inherited the compression setting from the parent storage pool

Actual results:
The new volume was successfully created with disabled compression option

    Fix Infinidat driver to inherit compression

    * Fixed Infinidat driver to inherit compression setting by default for
      all newly created volumes. Admin can set ``True`` or ``False`` for
      the ``infinidat_use_compression`` option in the driver section of
      cinder.conf to explicitly enable or disable compression setting for
      all newly created volumes. Or leave this option unset (commented out)
      for all created volumes to inherit their compression setting from
      their parent pool at creation time. The default value is unset.

    * Removed support for pre-v3.0 InfiniBox systems that do not support
      compression. These versions are end of life and no longer supported
      for a long time
