Document the configuration file

This patch adds a Documentation/config.txt file included by git-repo-config
and currently aggregating hopefully all the available git plumbing / core
porcelain configuration variables, as well as briefly describing the format.

It also updates an outdated bit of the example in git-repo-config(1).
