Refactor Huawei Volume driver
This patch attempts to refactor Huawei volume driver in liberty. We add a base driver to implement the basic functions. The sub-class will inherit from the base driver according to different storages. The following changes were made in this refactor: 1. Abstract a base class named HuaweiBaseDriver to make Huawei driver more universal. You can find it in the huawei_driver.py. 2. Put all static variables into the constants.py. 3. Rename rest_common.py to rest_client.py. rest_client.py stores the relevant methods implemented for Huawei driver. 4. Migrate some public methods from rest_client.py to huawei_utils.py, such as parse_xml_file(), _get_volume_type() and so on. 5. This refactor only involves structural adjustment and does not involve functional changes. Change-Id: I768889e2577a4d975397218eb31e89b42e08e04f Implements: blueprint refactor-huawei-volume-driver
