8ef02095fe Improve "Max total nodes in cluster reached" log. 2024-12-20 12:52:15 +00:00

4a89524f84 CA: enable the DRA feature gate whenever the DRA flag is passed 
This is needed so that the scheduler code correctly includes and
executes the DRA plugin.

We could just use the feature gate instead of the DRA flag in CA
(the feature gates flag is already there, just not really used),
but I guess there could be use-cases for having DRA enabled in the
cluster but not in CA (e.g. DRA being tested in the cluster, CA only
operating on non-DRA nodes/pods).

99282c08cb CA: automatically use BasicSnapshotStore when DRA is enabled 
By default CA is built with DeltaSnapshotStore, which isn't integrated
with DRA yet.

55388f1136 CA: plumb the DRA provider to SetClusterState callsites, grab and pass DRA snapshot 
The new logic is flag-guarded, it should be a no-op if DRA is disabled.

c5cb8a077d CA: add DRA object handling logic to PredicateSnapshot 
All added logic is behind the DRA flag guard, this should be a no-op
if the flag is disabled.

714ab661ca CA: implement calculating utilization for DRA resources 
The logic is very basic and will likely need to be revised, but it's
something for initial testing. Utilization of a given Pool is calculated
as the number of allocated devices in the pool divided by the number of
all devices in the pool. For scale-down purposes, the max utilization
of all Node-local Pools is used.

The new logic is mostly behind the DRA flag guard, so this should be a no-op
if the flag is disabled. The only difference should be that FilterOutUnremovable
marks a Node as unremovable if calculating utilization fails. Not sure
why this wasn't the case before, but I think we need it for DRA - if CA sees an
incomplete picture of a resource pool, we probably don't want to scale
the Node down.

479d7ce3d6 CA: implement a Provider for dynamicresources.Snapshot 
The Provider uses DRA object listers to create a Snapshot of the
DRA objects.

Kuba Tużnik
377639a8dc CA: implement dynamicresources.Snapshot for storing and modifying the state of DRA objects 
The Snapshot can hold all DRA objects in the cluster, and expose them
to the scheduler framework via the SharedDRAManager interface.

The state of the objects can be modified during autoscaling simulations
using the provided methods.

Fix a few CVEs in the e2e tests 
- https://pkg.go.dev/vuln/GO-2023-2113
- https://pkg.go.dev/vuln/GO-2024-3333
- https://pkg.go.dev/vuln/GO-2024-3321

Trivy discovered these. While not critical, since it's for e2e tests,
it's good to keep on top of these.

Bump golang.org/x/net to v0.33.0 
For this CVE: https://pkg.go.dev/vuln/GO-2024-3333

Whil it isn't used in the VPA, it's great to keep CVEs shipped with the
VPA down

720f5946fd Refactor NewAutoscalerError function. 
We will have two functions instead of one:
1. One that doesn't do formatting, like klog.Error
2. One that accepts formating, like klog.Errorf

The main reason behind this is to avoid go vet errors and have clear
interfaces to catch accidental bugs and rely on go vet to catch those
accidental bugs (or go test in go 1.24, as those are treated as errors).
