mpp_get_global_domains does not output expected results

[uramirez8707]

Describe the bug
The output to calls to mpp_get_global_domains is all zeroes instead of the expected results.

To Reproduce
The following code can reproduce the behavior:

call mpp_define_domains( (/1,nlon,1,nlat/), layout, Domain, xhalo=2, yhalo=2)

call mpp_get_global_domains(Domain,  xbegin=indices (:,1), xend=indices (:,2), &
                                     & ybegin=indices (:,3), yend=indices (:,4), &
                                     & xsize =indices (:,5), ysize=indices(:,6))

print *, "Indices:", indices

The output is all zeroes

Expected behavior
Either the output to mpp_get_global_domains should be correct, or the function should be deprecated and not used.

System Environment
This happens in any system

Additional context
N/A

It is working.. at least in cFMS? Let me double check

ok i'm seeing that you're calling get_global_domains and not get_global_domain 🙃

There is a slight difference between the two. mpp_get_global_domain returns the global domain for your given MPI-rank. mpp_get_global_domains is supposed to give you the global domain for all MPI-ranks within the domain. As we branch out into mosaics of tiles with non-uniform dimensions, this or another function should be able to provide the desired information.

@uramirez8707 - if we decide to deprecate or modify it to provide useful information, I have coded up an alternate routine for testing purposes that relies on the domain%tileList(:) information. Let me know if you want me to share the routine for debate on possible inclusion.
