Replace status with err in bash scripts

[DavidHuber-NOAA]

What new functionality do you need?

In order to use err_chk to be more EE2 compliant, variables such as status should be replaced with err. This will make it easier to address #294.

What are the requirements for the new functionality?

All cases of stat, status, etc are replaced with err when representing a fatal error or a script-ending error.

Acceptance Criteria

• All CI tests run successfully with no changes to products
• Any remaining stat, status, etc, variables are for non-fatal errors

I want to split this into two separate issues. This one can be about renaming the variables. We already have an existing issue addressing err_chk (#294) and are still deciding how exactly to do it.

Sounds good to me. I'll rework the title and description.
