Add support for OpenAPI version 3.1

[vbabuEM]

In order to support Layer 2 Config, the spec team is using conditionals(if-then-else) constructs and other conditional schema constructs. These are available in the 2020-12 version of JSON Schema. However Protocol Server currently supports OpenAPI 3.0 which supports only Draft 5 of JSON Schema (8 years old), which does not have these constructs.

Upgrade Protocol Server to support OpenAPI version 3.1. Please consider this request on priority.
