CMS MiniAOD support and ATLAS xAOD R22 Support

Two big changes in this release:

• CMS MiniAOD support (Run 2) is enabled. Only a limited number of collections, etc., are present - need a full type system run for it.
• ATLAS xAOD R22 is also supported. Same problems, however - only a limited number of collections are supported until full type support is enabled (in the front ends). This was done in a way as R21 and R22 code is common - so other than switching the transformer tag, R22 should run without any new servicex installation (and works locally).

There was also a set of work cleaning up the codebase (with lots more to do!). There was also some work done so that one can use MetaData to specify the transformer image. This works with LocalFile, and will eventually be lit up for servicex.
