Record history of this module at VA

Problem/Motivation

This is largely to record the original history of this at Department of Veterans Affairs.

• Epic (no real info present)
• Alt text prototype
• Server side validation
• Client side validation
• Tests
• Change management for rollout

This is the historical foundation of the alt_text_validation module, however the underlying code developed was narrowly focused and not extensible the way this module needs it to be. So most of it will be a re-write.
