RestClient exceptions and validation

In this section, we will introduce RestClientfor making API calls, and we will also look at how to handle exceptions globally in the application using @RestControllerAdvice with custom error messages (using problem details as described in RFC 7807).

Finally, we will look at how to use Bean validation to validate input at the application boundary.
