Feat/new workflow: Common Import Credentials

[rhofvendahl]

This PR creates a new workflow Common Import Credentials, describing a simple interaction between an importer, broker and CBP involving some common credentials.

[TallTed]

Could the title (and subsequent) of this workflow be changed from Common Import Credentials to Common Credentials for Imports? There might be another rephrasing that would be better. I'm just concerned with making it read more clearly, especially for non-English and non-Importer consumers who are just trying to learn.

Relatedly, please change the title of this PR to Feat/new workflow: Common Credentials for Imports so it's clearly different from other future/past Feat/new workflow PRs.

@TallTed the intention of the title was to describe these credentials as common constituents of an importation workflow. I was thinking the title suggests this in a succinct way, but I'd appreciate an outside view so if you feel strongly I can change it. Regardless, I've updated the description to reword things a bit - hopefully that helps some!

Multimodal BOL, Commercial Invoice don't apply to O&G, maybe remove OG?

@nissimsan just a warning about this number going up : /

[nissimsan]

Oh I know... Looking at it all day. Very sad! :(

[OR13]

what is the value of "Other" as a tag?

[mkhraisha]

Happy to merge out of band if name change goes through as ted requested and the OG comment is addressed

[rhofvendahl]

@mkhraisha I've improved the description in response to Ted's suggestion (see above), and made the requested changes. Ok to merge?
