We should never return a nil context because of the way this function is
typically used... e.g.
```

```
If there is an error `ctx` will be nil and any error handling may cause
an NPE if it tries to use `ctx`.

Add `remotes/certutil` functions for loading `ca.crt`, `client.cert`, and `client.key` into `tls.Config` from a directory like `/etc/docker/certs.d/<hostname>.
See https://docs.docker.com/engine/security/certificates/ .
Client applications including CRI plugin are expected to configure the resolver using these functions.
As an example, the `ctr` tool is extended to support `ctr images pull --certs-dir=/etc/docker/certs.d example.com/foo/bar:baz`.

EventLog is very old and provides a poor experience. We have supported
ETW for logging for a while, which is much better. We have also
observed an issue where EventLog keeps containerd.exe open, preventing
containerd from being upgraded to a new version. Due to all of this,
it makes sense to remove the old EventLog hook in favor of using ETW
logging on Windows as the primary diagnostic experience.

This adds a singleton `timeout` package that will allow services and user
to configure timeouts in the daemon. When a service wants to use a
timeout, it should declare a const and register it's default value
inside an `init()` function for that package. When the default config
is generated, we can use the `timeout` package to provide the available
timeout keys so that a user knows that they can configure.
These show up in the config as follows:
```toml
[timeouts]
"io.containerd.timeout.shim.cleanup" = 5
"io.containerd.timeout.shim.load" = 5
"io.containerd.timeout.shim.shutdown" = 3
"io.containerd.timeout.task.state" = 2
```
Timeouts in the config are specified in seconds.
Timeouts are very hard to get right and giving this power to the user to
configure things is a huge improvement. Machines can be faster and
slower and depending on the CPU or load of the machine, a timeout may
need to be adjusted.

Creating a console for containerd causes it to be inherited by any child
processes, which gives us performance and reliability improvements. See
comment in code for more information.
Another option considered here would be to invoke each child process
with the DETACHED_PROCESS flag. This would save us the containerd
console allocation. The difficulty of this approach would be ensuring
that all process invocation points have had this flag added, and that
any future invocations also use the flag.

This adds logging facilities at the shim level to provide minimal I/O
overhead and pluggable logging options. Log handling is done within the
shim so that all I/O, cpu, and memory can be charged to the container.
A sample logging driver setting up logging for a container the systemd
journal looks like this:
```go
package main
import (
"bufio"
"context"
"fmt"
"io"
"sync"
"github.com/containerd/containerd/runtime/v2/logging"
"github.com/coreos/go-systemd/journal"
)
func main() {
logging.Run(log)
}
func log(ctx context.Context, config *logging.Config, ready func() error) error {
// construct any log metadata for the container
vars := map[string]string{
"SYSLOG_IDENTIFIER": fmt.Sprintf("%s:%s", config.Namespace, config.ID),
}
var wg sync.WaitGroup
wg.Add(2)
// forward both stdout and stderr to the journal
go copy(&wg, config.Stdout, journal.PriInfo, vars)
go copy(&wg, config.Stderr, journal.PriErr, vars)
// signal that we are ready and setup for the container to be started
if err := ready(); err != nil {
return err
}
wg.Wait()
return nil
}
func copy(wg *sync.WaitGroup, r io.Reader, pri journal.Priority, vars map[string]string) {
defer wg.Done()
s := bufio.NewScanner(r)
for s.Scan() {
if s.Err() != nil {
return
}
journal.Send(s.Text(), pri, vars)

We can use cross repository push feature to reuse the existing blobs in
the same registry. Before make push fast, we know where the blob comes
from.
Use the `containerd.io/distribution.source. = [,]` as label format. For
example, the blob is downloaded by the docker.io/library/busybox:latest
and the label will be
containerd.io/distribution.source.docker.io = library/busybox
If the blob is shared by different repos in the same registry, the repo
name will be appended, like:
containerd.io/distribution.source.docker.io = library/busybox,x/y
NOTE:
1. no need to apply for legacy docker image schema1.
2. the concurrent fetch actions might miss some repo names in label, but
it is ok.
3. it is optional. no need to add label if the engine only uses images
not push.

This adds a way for users to programatically install containerd binary
dependencies.
With runtime v2 and new shim's being built, it will be a challenge to
get those onto machines. Users would have to find the link, download,
place it in their path, yada yada yada.
With this functionality of a managed `/opt` directory, containerd can
use existing image and distribution infra. to get binarys, shims, etc
onto the system.
Configuration:
*default:* `/opt/containerd`
*containerd config:*
```toml
[plugins.opt]
path = "/opt/mypath"
```
Usage:
*code:*
```go
image, err := client.Pull(ctx, "docker.io/crosbymichael/runc:latest")
client.Install(ctx, image)
```
*ctr:*
```bash
ctr content fetch docker.io/crosbymichael/runc:latest
ctr install docker.io/crosbymichael/runc:latest
```
You can manage versions and see what is running via standard image
commands.
Images:
These images MUST be small and only contain binaries.
```Dockerfile
FROM scratch
Add runc /bin/runc
```
Containerd will only extract files in `/bin` of the image.
Later on, we can add support for `/lib`.
The code adds a service to manage an `/opt/containerd` directory and
provide that path to callers via the introspection service.
How to Test:
Delete runc from your system.
```bash
> sudo ctr run --rm docker.io/library/redis:alpine redis

We introduce a WithSpecFromFile option combinator to allow creation
simpler creation of OCI specs from a file name. Often used as the first
option in a `SpecOpts` slice, it simplifies choosing between a local
file and the built-in default.
The code in `ctr run` has been updated to use the new option, with out
changing the order of operations or functionality present there.

Implements the various requirements for the runtime v2 code to abstract
away the unix/linux code into the appropriate platform level
abstractions to use the runtime v2 on Windows as well.
Adds support in the Makefile.windows to actually build the runtime v2
code for Windows by setting a shell environment BUILD_WINDOWS_V2=1
before calling make. (Note this disables the compilation of the Windows
runtime v1)

This patch changes the logs format to use a fixed-width timestamp,
matching the format that's used in dockerd.

Separate Fetch and Pull commands in client to distinguish
between platform specific and non-platform specific operations.
`ctr images pull` with all platforms will now unpack all platforms.
`ctr content fetch` now supports platform flags.
