[Mpi3-rma] missing RMA info keys

[Jim Dinan]

Hi Jeff,

I haven't looked at the text in a while -- alloc_shared_noncontig only 
makes sense in a call to MPI_Win_allocate_shared().  The other info keys 
were intended to be valid for all communicator creation routines.  If 
this isn't clear, then we should definitely correct it.  I created a 
ticket to make sure we remember to look at this:
