allow rails to be loaded in fix auth

When objects are serialized into yaml blobs in tables,
we need to load our whole environment to handle the deserialization

This typically happens with miq_requests.options

- add --allow-failures flag
- add note where error was found
- require standard rails when allow failures
- continue despite errors when allow failures
- display status, counts, and # errors
- change order of fixes
- reduce columns brought back
- sending error output to STDERR
