Support for json arrays on root level of body.

With using the groovy pact consumer there is no way, when using the withBody() dsl & matchers, to declare a json array on the root body. While I’ve heard of this being a bad idea for API design, it should still be supported.

I’ve tried looking at JsonBuilder as an example, it can build a root level array in a few different ways, seen here and here, but they don’t feel like the right fit for the PactBodyBuilder, so I’ve come up with my own pretty basic solution.

It involves the keyword ‘rootJsonArray’ in the dsl.

withBody() {
  rootJsonArray maxLike(10) {
    id identifier
      lineItems minLike(1) {
        id identifier
          amount numeric
          productCodes eachLike { code string('A100') }
      }
  }
}

I was also toying around with the idea of something like another dsl method similar to maxLike/minLike.

withBody() {
  orders rootJsonArray maxLike(10) {
    id identifier
      lineItems minLike(1) {
        id identifier
          amount numeric
          productCodes eachLike { code string('A100') }
      }
  }
}

but failed to get anything working quickly.

Found it, but it was only implemented for arrays on objects: https://github.com/DiUS/pact-jvm/issues/256#issuecomment-222295887

I’ll re-open that issue.

I thought this was supported, but I can’t seem to find the implementation.
