Add test examples for the resource server sample

- Add a post endpoint in /messages
- Changes the security config to require the read scope to GET a message and the write scope
to POST a new message.
- Changes the jwks of the mock server so I could create a new access token with the write scope.
- Creates tests and integration-tests for the POST endpoint.
- Changes the README to add an example of a POST request.

Fixes gh-7118
