cam6_4_047: update config component to handle new compset names

[jedwards4b]

This adds the C designation for concentration driven experiments, it's not clear to me if the emissions driven experiments will need the same date files or different ones so I've left that out for now.

Fixes issue #1077

@peverwhee I am going to need this change in alpha05b. I need to also add changes for HIST as well as 1850 so I'll work on that and push it back here. This is to support the C and E (Concentration and Emissions driven distinction) addition to compset names as documented in https://docs.google.com/spreadsheets/d/1nJl4lbbwBq60quyaERJ6OvVJxF4kDu4xX7zZenZgyB8/edit?usp=sharing.

ok thanks @jedwards4b. When you move this out of draft, I'll make it the next tag.

[jedwards4b]

I have added the C and E modifiers to compset names for Concentration and Emissions driven cases. As we do not yet have Emissions driven compsets these are both currently pointing to the same cam use cases and stream files.

@jedwards4b is this tag waiting on a resolution to #1189 ?

[jedwards4b]

I think that it would make sense for @fvitt
to add the use case here.
