[MNG-5344] update to slf4j 1.7.2 which allows the customization of the WARN level label. in the case of maven we vary slightly from all the standard logging implementations in that we use the string WARNING instead of WARN. once this change is made all the ITs pass again as all the failures were the result of string searches anchored on WARNING.
