Make NCMP integration tests use MockWebServer

Change from using MockRestServiceServer - which is only compatible
with RestTemplate - to MockWebServer, which will allow tests to work
using WebClient instead of RestTemplate.

+/**
+ * This class simulates responses from the DMI server in NCMP integration tests.
+ *
+ * It is to be used with a MockWebServer, using mockWebServer.setDispatcher(new DmiDispatcher()).
+ *
+ * It currently implements the following endpoints:
+ * - /actuator/health: healthcheck endpoint that responds with 200 OK / {"status":"UP"}
+ * - /dmi/v1/ch/{cmHandleId}/modules: returns module references for a CM handle
+ * - /dmi/v1/ch/{cmHandleId}/moduleResources: returns modules resources for a CM handle
+ *
+ * The module resource/reference responses are generated based on the module names in the map moduleNamesPerCmHandleId.
+ * To configure the DMI so that CM handle 'ch-1' will have modules 'M1' and 'M2', you may use:
+ *   dmiDispatcher.moduleNamesPerCmHandleId.put('ch-1', ['M1', 'M2']);
+ *
+ * To simulate the DMI not being available, the boolean isAvailable may be set to false, in which case the mock server
+ * will always respond with 503 Service Unavailable.
