HONEYCOMB-10: Add missing context parameter to *details structs

Some of the *details structures defined in vpe.api did
not have the context parameter that is used for request<->reply
matching. Without the context, it is difficult for upper
layers (users of vpp binary apis) to identify which reply
or details message belongs to which request

Tested manually using vat
