Maintain Utility: Add more Allocation parameters for database DSGs and Image Copy sizing.

Currently, the VOLALLO parameter applies to all database datasets including all DSGs as well as image copy datasets.  It would be useful to have separate command parameters for allocations of DSGs and Image copies because these datasets typically are not one blanket size.  Image copies are usually smaller than the database datasets and, DSG's contain a variety of segments different from the primary DSG which frequently results in varying DSG dataset sizes.  

Creating more granularity for the allocation of these datasets would benefit those who would like to exercise control over dataset allocations and prevent overallocation of these datasets.  Also, this would help to minimize the possibility of B37 errors that may result when MAINTAIN  requests more space than needed for DSGs and/or image copies.  

Currently, there is a VOLALLO, VOLALLOL and VOLALLOX parameter.  I believe that adding a parameter for image copy allocation such as VOLALLOI for example, would be useful.  And, for DSG's providing VOLALLO2/3/4 or VOLALLOB/C/D to control DSG allocation would be useful.
