Replace RestTemplate with WebClient in synchronous DMI calls

    - added DmiWebClientConfiguration
    - use WebClient in DmiRestClient
    - fixed unit tests
    - ingnored failing NCMP related integration tests (related to WebClient, will be fixed in a future patch)
    - encode query params for DMI requests
