Adding the mandatory field checks in PactDslJsonBody

[DurgaManasaMaruboyina]

Hello team,

Is there any way where we can add specific properties are mandatory like notEmpty matching rules in PactDslJsonBody. In consumer side tests we should be able to tell the specific properties are mandatory and they shouldn't be null or empty. We are writing contract tests for async message and using PactDslJsonBody to construct the pact message body.

You could use a regex like .+ that will match at least one character. But there is no mechanism to specify notEmpty at the moment.
