The new cadvisor version requires newer golang.org/x modules. Module
version selection raised crypto, mod, net, sync, sys, term, text, and
tools. golang.org/x/net moves from a pseudo-version to the v0.57.0
release, which includes the http2 fixes the pseudo-version pointed at.
cadvisor/lib no longer depends on github.com/gogo/protobuf. This change
removes cadvisor/lib from the gogo/protobuf dependants list in
hack/unwanted-dependencies.json.
github.com/google/cadvisor/lib v0.60.2 models the per-subsystem container
stats (Cpu, Memory, Network, DiskIo, Processes) as pointers, so a nil
again distinguishes "not collected" from a collected zero. Restore the
kubelet's original nil-checks in helper.go and cadvisor_stats_provider.go
(now equivalent to the pre-lib code), adapt the test fixtures and winstats
to build pointer sub-stats, and bump the vendored lib to v0.60.2.

Migrate the kubelet (and the kube-proxy conntrack helper) off the full github.com/google/cadvisor module onto the lean github.com/google/cadvisor/lib: repoint info/v1+info/v2 type usage to lib/model and the manager/fs/cache/etc. consumers to lib/*; regenerate the cadvisor.Interface mocks; keep the kubelet-pinned cAdvisor global flags via lib/cadvisorflags.
go.mod: require + replace github.com/google/cadvisor/lib (=> the dims/cadvisor/lib fork for now, until lib is tagged) and drop the full github.com/google/cadvisor module entirely; keep github.com/containerd/containerd/api at v1.11.0 (matching upstream master); add github.com/google/cadvisor to unwanted-dependencies.json unwantedModules so the full module cannot be re-vendored.
test/e2e_node: the one remaining consumer of the full module -- the node-e2e ResourceCollector, which used the v2 HTTP client (client/v2) + v2 API types (info/v2) -- now scrapes the standalone cAdvisor pod's /api/v2.1/stats directly over HTTP+JSON, so test/e2e_node depends on no cAdvisor package. No change to the kubelet's stats surfaces.
