Shared Ansible Dependencies

[TheTechromancer]

We have run into several situations (i.e. with ffuf) where multiple modules need access to the same dependency, but because of how preloading works, they each have to specify their own copy of the ansible playbook. It would be nice to compartmentalize this into a deps_helpers attribute, where we have a predefined selection of common tools such as ffuf, massdns, etc. available for any module to use. This would be a prerequisite to helperifying our DNS and web brute-forcing.
