@Amndeep7 is this ready for review even though it is in draft?

[Amndeep7]

@Bialogs I still need to flesh out the documentation, use aaron's account to make test data, and make a minor change to the prowler mapper, but otherwise yes for this portion. If we want to include the aws sdk mapper in this pr as well, then we can hold off until that's implemented, but that'll be sometime next week before I can work it.

This force push was to rebase on top of master

The automated tests are failing on ruby 2.5, coz of the difference method.

Feels bad man. Thanks for figuring that out for me. I'll try to find a different method to use / write it myself.

Life is suffering. Now it seems like the hash type doesn't support filter in 2.5

Working with Ryan made me realize there was an issue in the nist_tag code. Will fix tonight.

LGTM, thank you for making the updates.
Merging.
