Shutdown on Docker Daemon Error

[AdamMagaluk]

Should we be shutting down with a Fatal error if Docker Daemon returns an error here: https://github.com/30x/kiln/blob/master/pkg/kiln/docker_repo.go#L262

I cam across this with trying to add an envVar and didn't set the data right.

curl --fail -v -H 'Authorization:Bearer $TOKEN' -H Host:api.shipyard.dev -F file=@./fixture/app.zip -F name=test-app -F envVar=SOME_VAR http://192.168.99.100:30555/organizations/adammagaluk1/apps

Would replying with a 400 Bad Request be the right StatusCode? As well as the docker build error

We might not know its a Bad Request issue, it could be something else that is kiln's fault, so maybe just 500 Internal Server Error?
