    Fixed a bug around executor not able to use reserved resources.

    We were not unallocating the resources before checking if the
    executor resources were contained in the checkpointed resources
    on the agent.

> A custom executor or the built-in default executor cannot launch a task if they use reserved resources as part of {{ExecutorInfo}}. This mostly happens due to the fact that we don't unallocate the {{Resource}} when comparing it with the checkpointed resources on the agent:
> {code}
>   Resources checkpointedExecutorResources =
>     Resources(executorInfo.resources()).filter(needCheckpointing);
> {code}
> The fix can be as simple as changing this to:
> {code}
>   Resources checkpointedExecutorResources =
>     unallocated(executorInfo.resources()).filter(needCheckpointing);
> {code}
