Error handling is kinda sorta not a thing

[rgraciano]

The Lambda service needs to tell the user when they are missing information that's required for commands, and generally try a little harder (read: at all) to handle common errors.

Some needed features:

1. a call timeout that is < the lambda time for better recovery
2. I don't think error.message is correct, but these should be more user friendly errors anyway
3. SQS gets {error: ...} as a 200
