make exit code in failed state a pointer

[scott-cotton]

by manually adding the x-nullable property to the swagger.json

For context, see go-swagger/go-swagger#2166

LGTM.

Note that there is no need to do this change manually.
I would also make the following change in the API spec:

type FailedState struct {
	ExitCode     *int   `json:"exitCode" extensions:"x-nullable"`
	Message      string `json:"message,omitempty"`
	RetryAttempt bool   `json:"retryAttempt"`
}

LGTM.

	Message      string `json:"message,omitempty"`
	RetryAttempt bool   `json:"retryAttempt"`
}

Better in api spec, otherwise other thing to keep track
