Separate a new path parameter resource_plural to avoid key conflict

[yue9944882]

Some developers are confused by the "hairspace" character for the document-only listCustomObjectForAllNamespaces API model (Ref: kubernetes-client/java#3890) as the generated API method is not callable, Hence this PR adopts an alternative workaround from: OAI/OpenAPI-Specification#182 (comment)

Here is an example of how the generated code looks like:

    public APIlistCustomObjectForAllNamespacesRequest listCustomObjectForAllNamespaces(String group, String version, String resourcePlural) {
        return new APIlistCustomObjectForAllNamespacesRequest(group, version, resourcePlural);
    }
