mcipSUFFIX needs to be propagated

[prayner]

The motivation

Naming of files in this step needs to be consistent with running CMAQ
subsequently. At the moment MCIP generates files like GRID* and MET*
with suffixes like _1 and _2, these are hard coded in cmaq_config so
we need to either enforce consistency or check, this is currently done
by hand.

The proposed solution

I think we will need to check since it's quite possible we will
ultimately have several suffixes if they refer to various levels of domain.

Alternatives

We certainly have the possibility to enforce consistency if preferred

Additional context

[lewisjared]

I think the _2 is actually a bug in telling MCIP which grid to use. The scenarioTag was a string, but the code assumed it was a list so only used the first item.

For the docker runs the files are all suffixed with _220701_aust-test as intended. It might need some tweaks once it is running end to end.
