Update detect_machine.sh to be consistent with UFSWM

[RussTreadon-NOAA]

GDASApp has a copy of detect_machine.sh which is not consistent with detect_machine.sh in GSI PR #691. This issue is opened to work with the g-w team to get the correct detect_machine.sh in GDASApp ush/.

@HenryWinterbottom-NOAA and @aerorahul : from where do we get the official `detect_machine.sh which all EMC repos should be using?

[aerorahul]

@RussTreadon-NOAA Since the UFS-weather-model is usually the first component to be ported to a new system, we are treating it as the source for detect_machine.sh.
There is a PR in the ufs-weather-model under review at https://github.com/ufs-community/ufs-weather-model/pull/2111/files
One can grab that file from that PR or the global-workflow PR NOAA-EMC/global-workflow#2252

[RussTreadon-NOAA]

Thanks @aerorahul . @HenryWinterbottom-NOAA , shall I assign this issue to you for action at your convenience?

[HenryRWinterbottom]

@RussTreadon-NOAA Do you mean, as the detect_machine.sh changes within the UFSWM, I am responsible for updating the necessary GW submodules (including the GSI)?

If so, yes -- please assign to me.

[RussTreadon-NOAA]

@HenryWinterbottom-NOAA , GDASApp is cloned as a submodule from GW develop so I guess updating ush/detect_machine.sh in GDASApp is within the scope of what you are working on. Feel free to correct me if I'm wrong.

[RussTreadon-NOAA]

Assigning this issue to @HenryWinterbottom-NOAA . If this isn't within the scope of your work, reassign to me and I'll work with others to figure out how to proceed.

[aerorahul]

I think @HenryWinterbottom-NOAA can/will make a PR in the GDASapp when he is done with the other components.

[RussTreadon-NOAA]

Great! Thank you @aerorahul and @HenryWinterbottom-NOAA

Close with merger of PR #890 into develop.
