[Issue Type] Some mining model algorithm parameters are not supported [Issue Description] 
Previous versions of Analysis Services support using the MINIMUM_LEAF_CASES parameter with the Microsoft Decision Trees algorithm, and the MINIMUM_CLUSTER_CASES parameter with the Microsoft Clustering algorithm. Since SQL Server 2005 Analysis Services, both of these parameters have been renamed to MINIMUM_SUPPORT. If these parameters were used in mining models created using the previous version of Analysis Services , the parameters are not migrated.
