> First test generic placeholder pre-emption: 
> Create a job with placeholders:
> small enough to fits in the queue
> larger than the free space of the queue.
> This will leave the placeholder running for a long time as they need to timeout.
> Hopefully it generates a node that is fully loaded with gang placeholders.
> Then create a daemon set that must run on the node.
> The size of the daemon set must be large enough so that it does not fit on the node
> That should trigger the placeholder pre-emption.
> Before the fix: the placeholder data for the app does not show that the placeholder was removed
> After the fix: the placeholder data for the app shows a removed placeholder
> Second test is node removal with placeholders:
> Create a job with placeholders:
> small enough to fits in the queue
> larger than the free space of the queue.
> This will leave the placeholder running for a long time as they need to timeout.
> remove the node with at least 1 placeholder
> Before the fix: the placeholder data for the app does not show that the placeholder was removed
> After the fix: the placeholder data for the app shows a removed placeholder
> Third test is kill a placeholder:
> Create a job with placeholders:
> small enough to fits in the queue
> larger than the free space of the queue.
> This will leave the placeholder running for a long time as they need to timeout.
> mimic a removal of the placeholder via kubectl by creating a allocation release request and send that to the partition with the termination type STOPPED_BY_RM
> Before the fix: the placeholder data for the app does not show that the placeholder was removed
> After the fix: the placeholder data for the app shows a removed placeholder
> Working config:
> queue quota max size: 16GB / 16cpu
> nodes: 2 * 8GB / 8 cpu
> create an application with allocation: 4 GB / 4 cpu
> create an gang application requesting: 7 * 2GB / 2cpu
> create a daemon set pod for one of the nodes asking for 1GB / 1 cpu
