service plugin to handle CRI sandboxes and containers.

Add a common NRI 'service' plugin. It takes care of relaying
requests and respones to and from NRI (external NRI plugins)
and the high-level containerd namespace-independent logic of
applying NRI container adjustments and updates to actual CRI
and other containers.
The namespace-dependent details of the necessary container
manipulation operations are to be implemented by namespace-
specific adaptations. This NRI plugin defines the API which
such adaptations need to implement.

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.

no leading space, required colon (`:`) and linters.
- remove "nolint" comments for errcheck, which is disabled in our config.

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 part of the effort of getting hypervisor isolated windows container
support working for the CRI entrypoint here, add the runhcs-wcow-hypervisor
handler for the default config. This sets the correct SandboxIsolation
value that the Windows shim uses to differentiate process vs. hypervisor
isolation. This change additionally sets the wcow-process runtime to
passthrough io.microsoft.container* annotations and the hypervisor runtime
to accept io.microsoft.virtualmachine* annotations.
Note that for K8s users this runtime handler will need to be configured by
creating the corresponding RuntimeClass resources on the cluster as it's
not the default runtime.

It is follow-up of #7254. This commit will increase ReadHeaderTimeout
from 3s to 30m, which prevent from unexpected timeout when the node is
running with high-load. 30 Minutes is longer enough to get close to
before what #7254 changes.
And ideally, we should allow user to configure the streaming server if
the users want this feature.
