This release adds the ability to filter properties (Services, RPCs, Fields, Enum values) from being rendered in the OpenAPI v2 spec generated by protoc-gen-openapiv2. See https://grpc-ecosystem.github.io/grpc-gateway/docs/mapping/customizing_openapi_output/#hiding-fields-methods-services-and-enum-values for more information about this new exciting capability!

Other new features:

• A new option to generate the OpenAPI v2 spec in YAML format
• Allow serving a health endpoint at an arbitrary path with the new WithHealthEndpointAt ServeMux option
