Refactor docs related to DCOs

[reviewed by @ben-albrecht and partially by @ronawho ]

This refactors our docs related to DCOs in the following ways:

  • moves most of the details relating to DCOs into a new file, DCO.rst,
    in order to simplify CONTRIBUTING.md, ContributorInfo.rst, and

  • introduces additional ways of signing commits for completeness and
    because the file template approach wasn’t as bulletproof as hoped.
    Pluses and minuses are given for each.

  • refactors CONTRIBUTING.md to make its role relative to
    ContributorInfo.rst clearer

  • makes contributorAgreements/README.md more of a historical
    placeholder and less of a restatement of the DCO.

Modified Files:
A doc/rst/developer/bestPractices/DCO.rst
M doc/rst/developer/bestPractices/ContributorInfo.rst
M doc/rst/developer/contributorAgreements/README.md
