Clear and consistent documentation

[tdsmith]

We should have a single, correct, easy-to-find place for data scientists to find instructions on contributing reports to knowledge repositories.

Some places that people might look or that have some information include:
https://github.com/mozilla/docere
https://github.com/mozilla-services/mozilla-private-reports
data science mana page and onboarding guide
Docere Howto preso https://docs.google.com/presentation/d/1CeKasusulfaYzBMf2IO_wHRMkcJ6A7exZWFSYvkPYTk/edit#slide=id.g951e9dc6cf_0_28

We should choose a canonical place and have other sources point to it.
