Distributed version of UseJacksonForJsonPathRule JUnit Rule that configures json-path to use
{@code JacksonJsonProvider} in all DUnit VMs (except for the hidden Locator VM) in addition to
the JVM running JUnit (known as the Controller VM).

<p>
DistributedUseJacksonForJsonPathRule can be used in tests that need to use json-path-assert:

<pre>
{@literal @}ClassRule
public static DistributedUseJacksonForJsonPathRule useJacksonForJsonPathRule = new DistributedUseJacksonForJsonPathRule();

{@literal @}Test
public void hasAssertionsUsingJsonPathMatchers() {
  ...
  assertThat(json, isJson());
  assertThat(json, hasJsonPath("$.result"));
}
</pre>
