> When launching a task, we need to validate:
>  # Only CPU and memory are supported as resource limits.
>  # Resource limit must be larger than resource request.
>  ** We need to be careful about the command task case, in which case we add an allowance (0.1 CPUs and 32MB memory, see [here|https://github.com/apache/mesos/blob/1.9.0/src/slave/slave.cpp#L6663:L6677] for details) for the executor, so we need to validate task resource limit is larger than task resource request + this allowance, otherwise the executor will be launched with limits < requests.
>  # `TaskInfo` can only include resource limits when the relevant agent possesses the TASK_RESOURCE_LIMITS capability.
>  # The value of the field `shared_cgroups` should be same for all the tasks launched by a single default executor.
>  # It is not allowed to set resource limits for the task which has the field `shared_cgroups` set as true.
