Ian Wienand c9b4b01187 Add guidelines on variable naming ... This captures some discussion over the scoping of variable names during some recent role development. It tries to provide some guidelines to prefixing of global variable names in roles and "module-like" roles. Since "deprecation.rst" is now holding a few different things, it makes more sense as "policy.rst". Reorganise to be nested in one more level, and add a contents section to help find sections easier.
