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.

This updates the test to:
- Use correctly formatted values for RequiredPlugins and DisabledPlugins (values
are expected to have a `io.containerd.` prefix). While not needed for the test
to pass (no validation is performed), it's good to have these values in the
correct format (in case we want to add validation at this stage).
- Set a `Version` for both (as version 1 / no version was deprecated)
The `Version` field in this test was used to verify the "integer override"
behavior; setting "Version: 2" for both would no longer cover that case. As there
are only 2 integer fields in the config (Version and OOMScore) and OOMScore was
already used in the test, I added separate test-cases for that.
Looking at the test, we should consider what we want the behaviour to be if the
override file does not specify a version (implicitly: version 1), or if the version
is different from the original one; do we want mergeConfig() to produce an error
when merging a v2 config with a v1 config (or v3 with v2)?

In Go 1.16 `net.ErrClosed` was exported, removing the need to check the
exact text of "use of closed network connection". The stdlib's net listeners
are all setup for this to be a reality, but on Windows containerd uses the
the go-winio projects named pipe implementation as the listener for services.
Before version 0.6.0 this project returned a different error named
`ErrPipeListenerClosed` for using a closed pipe, where this error was just
an `errors.New` with the same text as `net.ErrClosed`, so checking against
`net.ErrClosed` wasn't possible.
Starting in 0.6.0 go-winio has that error assigned to `net.ErrClosed` directly
so this *should* be alright to finally change.

This patch adds support for a container annotation and two separate
pod annotations for controlling the blockio class of containers.
The container annotation can be used by a CRI client:
"io.kubernetes.cri.blockio-class"
Pod annotations specify the blockio class in the K8s pod spec level:
"blockio.resources.beta.kubernetes.io/pod"
(pod-wide default for all containers within)
"blockio.resources.beta.kubernetes.io/container.<container_name>"
(container-specific overrides)
Correspondingly, this patch adds support for --blockio-class and
--blockio-config-file to ctr, too.
This implementation follows the resource class annotation pattern
introduced in RDT and merged in commit 893701220.
