In golang when copy a slice, if the slice is initialized with a
desired length, then appending to it will cause the size double.

Add a new config as sandbox controller mod, which can be either
"podsandbox" or "shim". If empty, set it to default "podsandbox"
when CRI plugin inits.

Go 1.18 and up now provides a strings.Cut() which is better suited for
splitting key/value pairs (and similar constructs), and performs better:
```go
func BenchmarkSplit(b *testing.B) {
b.ReportAllocs()
data := []string{"12hello=world", "12hello=", "12=hello", "12hello"}
for i := 0; i < b.N; i++ {
for _, s := range data {
_ = strings.SplitN(s, "=", 2)[0]
}
}
}
func BenchmarkCut(b *testing.B) {
b.ReportAllocs()
data := []string{"12hello=world", "12hello=", "12=hello", "12hello"}
for i := 0; i < b.N; i++ {
for _, s := range data {
_, _, _ = strings.Cut(s, "=")
}
}
}
```
BenchmarkSplit
BenchmarkSplit-10 8244206 128.0 ns/op 128 B/op 4 allocs/op
BenchmarkCut
BenchmarkCut-10 54411998 21.80 ns/op 0 B/op 0 allocs/op
While looking at occurrences of `strings.Split()`, I also updated some for alternatives,
or added some constraints; for cases where an specific number of items is expected, I used `strings.SplitN()`
with a suitable limit. This prevents (theoretical) unlimited splits.

Add spans around image unpack operations
Use image.ref to denote image name and image.id for the image config digest
Add top-level spand and record errors in the CRI instrumentation service
Old TODO stating that pkg/cri/opts's `WithWindowsNetworkNamespace`
should be moved to the main containerd pkg was out of date as thats
already been done (well, to the /oci package). This just removes it
and swaps all uses of `WithWindowsNetworkNamespace` to the oci
packages impl.

Remove nolint-comments that weren't hit by linters, and remove the "structcheck"
and "varcheck" linters, as they have been deprecated:
WARN [runner] The linter 'structcheck' is deprecated (since v1.49.0) due to: The owner seems to have abandoned the linter. Replaced by unused.
WARN [runner] The linter 'varcheck' is deprecated (since v1.49.0) due to: The owner seems to have abandoned the linter. Replaced by unused.
WARN [linters context] structcheck is disabled because of generics. You can track the evolution of the generics support by following the https://github.com/golangci/golangci-lint/issues/2649.

- fix "nolint" comments to be in the correct format (`//nolint:<linters>[,<linter>`
no leading space, required colon (`:`) and linters.
- remove "nolint" comments for errcheck, which is disabled in our config.
- remove "nolint" comments that were no longer needed (nolintlint).
- where known, add a comment describing why a "nolint" was applied.

This `//nolint` was added in f5c7ac9272
to suppress warnings about the `NameToCertificate` function being deprecated:
// Deprecated: NameToCertificate only allows associating a single certificate
// with a given name. Leave that field nil to let the library select the first
// compatible chain from Certificates.
Looking at that, it was deprecated in Go 1.14 through
eb93c684d4
(https://go-review.googlesource.com/c/go/+/205059), which describes:
crypto/tls: select only compatible chains from Certificates
Now that we have a full implementation of the logic to check certificate
compatibility, we can let applications just list multiple chains in
Certificates (for example, an RSA and an ECDSA one) and choose the most
appropriate automatically.
NameToCertificate only maps each name to one chain, so simply deprecate
it, and while at it simplify its implementation by not stripping
trailing dots from the SNI (which is specified not to have any, see RFC
6066, Section 3) and by not supporting multi-level wildcards, which are
not a thing in the WebPKI (and in crypto/x509).
We should at least have a comment describing why we are ignoring this, but preferably
review whether we should still use it.

Currently CDI registry is reconfigured on every
WithCDI call, which is a relatively heavy operation.
This happens because cdi.GetRegistry(cdi.WithSpecDirs(cdiSpecDirs...))
unconditionally reconfigures the registry (clears fs notify watch,
sets up new watch, rescans directories).
Moving configuration to the criService.initPlatform should result
in performing registry configuration only once on the service start.

As WithCDI is CRI-only API it makes sense to move it
out of oci module.
This move can also fix possible issues with this API when
CRI plugin is disabled.
