This commit attemts to support containerd on darwin platform. With an
external runtime shim, ctr run should work with, for instance,
--runtime=io.containerd.runu.v1. An example of runtime and shim is
managed under different repository (github.com/ukontainer/runu/).

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.

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.

Add support for an 'env' field to the StreamProcessor configuration
and append the environment variables found there to the os.Environ()
array.
The env field takes environment variables in the form of key=value.

Fix restoring from a checkpoint image always getting skipped when no checkpoint image path is set. As one restores either from an image OR a path, this makes no sense.

When containerd is restarted, only v1 tasks are monitored again. This
leads to the lack of existing v2 task metrics.

Cleanup is an optional method a snapshotter may implement.
Cleanup can be used to cleanup resources after a snapshot
has been removed. This function allows a snapshotter to defer
longer resource cleanup until after snapshot removals are
completed. Adding this to the API allows proxy snapshotters
to leverage this enhancement.

* only shim v2 runc v2 ("io.containerd.runc.v2") is supported
* only PID metrics is implemented. Others should be implemented in separate PRs.
* lots of code duplication in v1 metrics and v2 metrics. Dedupe should be separate PR.

Proxy plugins are keyed only on the identifier, the type
is specified within the proxy plugin configuration which
maps to the full URI. The proxy plugin configuration is
not passed to the plugin for configuration like other
plugins.

Do not rely on toml metadata when decoding plugin's configs as it's not possible to merge toml.MetaData structs during import.
