Populate Attributes for HostServices

Inside the start payload istep a set of FAPI attributes will
 be read and copied into a specified location of mainstore so
 that HostServices runtime code can access them.
There are 4 files that will be shared with HostServices code:
- attribute_structs.H : common structures used to define data
- hsvc_sysdata.C : list of required system attributes
- hsvc_procdata.C : list of required proc attributes
- hsvc_exdata.C : list of required ex attributes
