Add basic intiialization of opentelemetry including minimum support to
be able to read open telemetry config from config.toml and initialize
exporter. Tracer is initialized and ready to be be used for creating
spans, sub spans etc. With no opentelemetry configuration enabled in
config file, this patch is a no-op.
Basic config stub to be added to use opentelemetry is to add following
in config.toml. We use otlp exporter with default port 4317.
[otel]
exporter_name = "otlp"
exporter_endpoint = "0.0.0.1:4317"
otel-collector binary needs to run listening at the same port.

systemd uses SIGRTMIN+n signals, but containerd didn't support the signals
since Go's sys/unix doesn't support them.
This change introduces SIGRTMIN+n handling by utilizing moby/sys/signal.
Fixes#5402.

add '--snapshotter-labels' in ctr run and ctr c create
which can pass labels to snappshotter on preparing new
snapshot.
Pass command label to snapshotter can help it determine
which kind of writable snapshots should be provide.
For some snapshotter, such as overlaybd:
( https://github.com/alibaba/accelerated-container-image ),
it can provide 2 kind of writable snapshot (overlayfs dir or
blockdevice) by command label values.

FreeBSD mount options may have embedded = characters. For example,
devfs(5) supports the `ruleset` option which can be passed as
`ruleset=4` to indicate that ruleset 4 should be used.

According to the doc about `config.toml` of containerd:
```
If no version number is specified inside the config file then it is assumed to
be a version 1 config and parsed as such.
```
However, it's not true recently.
This will break the backward-compatibility in some environment.
This commit fixes this issue.

containerd-stress utility needs to be able to run with snapshotter
passed by user in cli in order to be able to stress test snapshotters.
This adds a cli option --snapshotter="<snapshotter-name>"

This fixes following warning message by changing the default runtime
to io.containerd.runc.v2 and does not require user to set the runtime
from command line anymore.
"WARN[2021-03-17T21:11:01.441207858Z] runtime v1 is deprecated since
containerd v1.4, consider using runtime v2"

This enables cases where devices exist in a subdirectory of /dev,
particularly where those device names are not portable across machines,
which makes it problematic to specify from a runtime such as cri.
Added this to `ctr` as well so I could test that the code at least
works.
