release/1.9.0: add provides's for hdf5, netcdf-c, esmf, python

[AlexanderRichert-NOAA]

This stack adds a dummy provides to each of hdf5, netcdf-c, esmf, and python so they can be used as part of the lmod hierarchy for WCOSS2. Tested on Acorn.

Part of NOAA-EMC/WCOSS2-requests#19

I like this idea, but does it mean we automatically have this model hierarchy structure on all systems? And can we call those packages _virtual instead of just _virt? The three letters hardly make any difference for typing etc.

[AlexanderRichert-NOAA]

No, it doesn't get automatically included in the hierarchy, it's only if you add those to modules:default:lmod:hierarchy. So for the moment this is just for WCOSS2 once that PR gets merged. And yes, I'll rename them to '_virtual'.

Perfect, thanks!

@AlexanderRichert-NOAA This is still open. Does this need to go into the release branch for the updated wcoss2 config?

[AlexanderRichert-NOAA]

Yes
