Validate ext_authz OkResponse header append actions
Commit Message: Validate ext_authz OkResponse header append actions
Additional Description:This PR adds validation (and removes sentinel value check) to the ext authz grpc client. If an invalid header append action is found and validate_mutations is true, the response and thus downstream request will be rejected. If validation_mutations is false, invalid actions are ignored.
Risk Level: low
Testing: unit / integration tests added
