relocate DISA compliance roles

[jce-redhat]

the DISA compliance roles are external third party content being "vendored" in under the collections/ directory. they should be moved under roles/ instead, just like the external redhatofficial.* roles currently under roles/.

Hey @jce-redhat

I get the idea of moving them to roles/, but what's the big win over leaving them in collections/? Collections format seem pretty up-to-date.

Also, about linting third-party stuff, what if we just skip linting for these and keep them in a separate collection?
