Migrate K8sDatapathBandwidthTest to newer testing infrastructure #44165
Description
Migrate K8sDatapathBandwidthTest to newer testing infrastructure
These tests should be removed from the test/k8s suite and replaced with either component-based testing (preferred) or end-to-end tests via cilium-cli:
$ git grep K8sDatapathBandwidthTest | grep -v cliFocus
.github/actions/ginkgo/main-focus.yaml: # K8sDatapathBandwidthTest Checks Bandwidth Rate-Limiting Checks Pod to Pod bandwidth, direct routing
.github/actions/ginkgo/main-focus.yaml: # K8sDatapathBandwidthTest Checks Bandwidth Rate-Limiting Checks Pod to Pod bandwidth, geneve tunneling
.github/actions/ginkgo/main-focus.yaml: # K8sDatapathBandwidthTest Checks Bandwidth Rate-Limiting Checks Pod to Pod bandwidth, vxlan tunneling
test/ginkgo-ext/junit_reporter.go: case "K8sDatapathBandwidthTest":
test/k8s/bandwidth.go:var _ = SkipDescribeIf(helpers.DoesNotRunOnNetNextKernel, "K8sDatapathBandwidthTest", func() {
