Delay scale-up including GPU request
...
Nodes with GPU are expensive and it's likely a bunch of pods
using them will be created in a batch. In this case we can
wait a bit for all pods to be created to make more efficient
scale-up decision.

Add a workaround for scaling of VMs with GPUs
...
When a machine with GPU becomes ready it can take
up to 15 minutes before it reports that GPU is allocatable.
This can cause Cluster Autoscaler to trigger a second
unnecessary scale up.
The workaround sets allocatable to capacity for GPU so that
a node that waits for GPUs to become ready to use will be
considered as a place where pods requesting GPUs can be
scheduled.

Skip nodes in min-sized groups in scale-down simulation
...
Currently we track if those nodes can be removed and only
skip them at the execution step. Since checking if node is
unneeded is pretty expensive it's better to filter them out
early.

we haven't heard about any user changing it to false and
after removing check on PodScheduled condition setting it
to false would basically break CA.
