Allow Virtual Concurrent Copy (VCC) to dynamically allocate Working-Space Data Set(s)

Virtual Concurrent Copy currently requires each installation to pre-define/allocate the Working-Space Data Set necessary to contain the PIT track images.  There is no easy way for the installation to know what the appropriate size for these data sets should be and it is necessary to just "guess" or use SMF data to determine what is appropriate.  But if the installation defines the data set too small, the concurrent copy can fail.  VCC should be able to dynamically determine the necessary size (or at least use some default size) and allocate these data sets as necessary instead of forcing each installation to pre-define them.  This could work similar to the way that the SVC Dump process can dynamically define the SVC Dump data set when an SVC dump is being generated.  If necessary, a new ANTMIN00 parameter could be used to allow/disallow this new function as well as manage the size of the data set--to set a maximum size, for example.
