sling:OsgiConfig for multiple run modes

You can have multiple run modes and have CQ (or Sling.. I don't know) select proper sling:OsgiConfigs.

For example, if your run modes are a,b config.a.b are applied:
author,production

• /apps/<foo>/config.author.production/*

author,staging

• /apps/<foo>/config.author.staging/*

publish,production

• /apps/<foo>/config.publish.production/*

Probably order of run modes are important. And I'm not sure if more than two run modes will work.

TODO:
author,production,foo,bar

• /apps/<foo>/config.author.production.foo.bar/*
• /apps/<bar>/config.author.production.foo.bar/*
• /apps/<foo>/config/config.author.production.foo.bar/*
• /apps/<foo>/config.production.bar.foo.author/*

test what configuration is selected...
