Provide better healthchecks

[oleg-nenashev]

Proposal

Follow-up to #25. Once wiremock/wiremock#2164 is implemented in WireMock Core and added to the WireMock Docker, it would be nice to adapt the code to use better healthcheck endpoint for newer versions of the container image

While wiremock/wiremock#2164 is not implemented , as noted by @wallid , we need another health check that would at least verify that the instance can serve some mock endpoints. It will be also useful for any 2.x tests

I suggest the following:

1. If any withMapping() method is passed, note that the mappings should be present
2. If so, also verify the response of /__admin/mappings and ensure that the response is not null

Now we can do better healtchecks starting from WireMock 3.0
