Currently kube-proxy defaults the min-sync-period for
iptables to 0. However, as explained by Dan Winship,
"With minSyncPeriod: 0, you run iptables-restore 100 times.
With minSyncPeriod: 1s , you run iptables-restore once.
With minSyncPeriod: 10s , you also run iptables-restore once,
but you might have to wait 10 seconds first"
Previously, we didn't check the contents of the result after calling out
to the plugin endpoint. This could have resulted in errors if the plugin
returned either 'nil' or an empty result. This patch fixes this.
Previously, we were passing the variable 'devices' to this function,
when we should have been passing 'allocated'. This bug crept in due to a
variable name change that didn't propogate its way through the entire
function. The tests added in the previous commit would have caught this.
If no potential victims could be found, there is no need to evaluate the node
again, since its state didn't change.
It's safe to return and thus prevent scheduling from running the filter plugins
again.
NOTE:
A node that is filtered out by filter plugins could pass the filter plugins if
there is a change on that node, i.e. pods termination on that node.
Previously, this could be either caught by the normal `schedule` or `preempt` (pods
are terminated when the preemption logic tries to find the nodes and re-evaluate
the filter plugins.)
Actually, this shouldn't be taken care by the preemption, consider the routine
of `schedule` is always running when the interval is "zero", let `schedule`
take care of it will release `preempt` from something irrelevant with the `preemption`.
Due to above reason, couple of testcase as well as the logic of checking the existence
of victim pods are removed as it will never happen after the change.

This uses the information provided by a CSI driver deployment for
checking whether a node has access to enough storage to create the
currently unbound volumes, if the CSI driver opts into that checking
with CSIDriver.Spec.VolumeCapacity != false.
This resolves a TODO from commit 95b530366a.
