    Ignore JSON decode error in request log.

    For DELETE requests with no request body or "Content-Length" field, the
    expected return value for "hasattr(rest_state.request, 'json')" would be
    False and for "rest_state.request.json" would be an empty string.
    Instead, what occurs is that both "hasattr(rest_state.request, 'json')"
    and "rest_state.request.json" are throwing JSON decode exceptions in
    this case. This change adds tolerance for this exception. This is done
    because it is not known all the possible request conditions that may
    cause this exception to be thrown.

    Test Plan:

    PASS: Send a delete request through the CLI to subcloud-group and
           verify if any exception shows up dcmanager-api logs.
