Config transformers and filters now error if no matches

[matthchr]

What this PR does / why we need it:

• Ensure that all config transformers and filters
  raise an error by default if they don't match anything.
• Removed config options that had no matches.

I got tired of fighting with it for VMSS (where I'm mucking with the config quite a bit to make sure the resource comes out looking good).
