Implement NetApp ONTAP REST API Client

Registered by Felipe Rodrigues

Currently, NetApp ONTAP Manila driver implements ZAPI client [0] to communicate with ONTAP back ends.
ZAPI client code sends HTTP(S) POST methods carrying XML data describing the operation to be issued, and receives responses containing XML data to be parsed.

ONTAP >= 9.6 provides a RESTful API [1] as an alternative to ZAPI. Also, the ZAPI will be deprecate soon.

This blueprint is to implement RESTful API client in the ONTAP NetApp driver to communicate with ONTAP back ends.
