A few changes necessary to make driver compatible with
ScaleIO version 1.3x
- refactored SIO REST calls to go through common code
- obtain REST API version number dynamically
- allow configuration to override what API version to use
- Make API calls based upon API version
- Add unit tests to validate calls to retrieve version
This commit adds a new configuration option, called:
sio_server_api_version
- This can be used to override the value
retrieved from the ScaleIO server at runtime
- This is helpful for manual testing, but should
not be needed in a production environment
