Add documentation on the various hosting services we support.
Review Request #8722 — Created Feb. 7, 2017 and submitted
This fleshes out our documentation on configuring repositories to include instructions on each hosting service we support. For most, this is just basic instructions on the types of repositories supported, how to link accounts, and how to configure the repository information for the given service. Some docs go into more detail on extra configuration and features. For instance, the GitHub documentation talks about how to configure a custom OAuth app and how to request/grant permission on organizations. This also includes documentation on VisualStudio.com and GitHub Enterprise. While included from Power Pack, having all repository configuration docs in one place is ideal for those getting started. The Power Pack documentation will be updated later to point to this. Documentation for Kiln has been intentionally left out, as Fog Creek has renamed Kiln and changed some aspects of it. We'll need to sort out our hosting service support before useful docs can be written.
Built/viewed the docs and tested links.
Checked for spelling errors.
Tested each set of docs against the realities of the hosting service.
