描述
Currently, we just bubble up any yaml-cpp exceptions back to the client, but the error message is out of context of what is really wrong. For example, if a user creates a cloud-init config with incorrect yaml, an error could look like:
launch failed: operator[] call on a scalar
As can be seen, it's not clear where the error is.
We should catch the yaml-cpp exceptions and make it a more meaningful message to pass to the client and user.
