[chore] COC and Contributing docs

[BeauBouchard]

We want to have a copy of the COC and Contributing pages appear in all readmes from links. we can consolidate those to a single org repo, or put them in the /docs/ of the repos.

I think we did it previously in /shrewd/ but I am very open to doing it differently if we are going to have the same policy for all public repos.

• Link to COC in README of repo
  • We previously used the Contributor Covenant Homepage, version v1.4.0 as hosted in the /shrewd/ repo.
• Link to Contributing docs in README of repo
• (optional) Create COC in repo in /docs folder.
• (optional) Create Contributing in repo in /docs folder.
• (or optional) Create a single ORG repo that has those documents and link to them from the above links.
