Description

When sending a task launch using the 1.0.x protos and the legacy (non-http) API, tasks with a healthcheck defined are rejected (TASK_ERROR) because the 'type' field is not set.

This field is marked optional in the proto and is not available before 1.1.0, so it should not be required in order to keep the mesos v1 api compatibility promise.

For backwards compatibility temporarily allow the use case when command health check is set without a type.
