Polish "Use Jackson configuration with JsonPath"

Browse Source 
Polish contribution to use a factory method in `AbstractJsonMarshalTester`
rather than additional constructor arguments.

Also change the `JsonContent` tests so that the `Configuration` constructor
is package private. This keeps JsonPath classes out of our public API, at
the expense of limiting custom JsonPath configurations to just our code.

See gh-16629
