Create glossary

[radu-matei]

There are a lot of terms that we use regularly when talking about the registry — there should be one file that contains all the definitions.

A few examples of project glossaries:

• glossary.md is a popular top-level doc. Examples:
  • https://osf.io/4qu6n/?ref=5fc24aec086b0ec1582d59882ac72753a20b6778
  • https://sourcegraph.com/github.com/sourcegraph/sourcegraph/-/blob/enterprise/docs/glossary.md
• K8s breaks individual topics into separate md's like kubernetes.md and rendered at https://kubernetes.io/docs/reference/glossary/?fundamental=true.
• Some call this terminology: https://github.com/kubernetes-sigs/service-catalog/blob/master/terminology.md

I plan to write a flat glossary.md at the root of the repo.

A glossary.md file at the root of the repo sounds great!
