Add spans around image unpack operations
Use image.ref to denote image name and image.id for the image config digest
Add top-level spand and record errors in the CRI instrumentation service
When support for http/protobuf was added, the OTLP tracing processor
plugin was mistakenly changed to return a raw OTLP exporter instance.
Consequently, the type-assertion to a trace.SpanProcessor inside the
tracing pluigin would panic if the processor plugin was configured.
Modify the OTLP plugin to return a BatchSpanProcessor derived from the
exporter once more.

- insecure.NewCredential was simply wrong. It has to use
otlptracegrpc.WithInsecure to disable TLS.
- context.WithTimeout is nice to have, in case the endpoint is not
correctly configured.
Otherwise, the plugin initialization blocks indefinitely.
- grpc.WithReturnConnectionError is nice to have.
Otherwise, otlptracegrpc.New returns "context deadline exceeded"
without underlying errors.
- TraceSamplingRatio should be 1.0 by default.
Otherwise, users need to configure both io.containerd.internal.v1.tracing
and io.containerd.tracing.processor.v1.otlp.

This fixes the issue with the usage of the deprecated attribute.Any
function that original caused build issues.

This adds valuable logging data to the open telemetry traces.
When the trace is not recording we don't bother doing anything as it is
relatively expensive to convert logrus data to otel just due to the
nature of how logrus works.
The way this works is that we now set a context on the logrus.Entry that
gets passed around which the hook then uses to determine if there is an
active span to forward the logs to.

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.
