Import the log module directly, instead of using the aliases that are
provided in the log package. This helps find code-paths that still depend
on the old location, and that haven't migrated yet to the new module.

These are standard environment variables described by the otel spec in
https://opentelemetry.io/docs/specs/otel/configuration/sdk-environment-variables/.
The old config options are removed
Also since otel will by default try to connect to https://localhost:4318
if no endpoint is set, this will also just disable the otlp plugin when
there is no endpoint so we don't have otel continuously trying to
connect to the default endpoint, littering the logs with connection
failure messages and collecting traces that won't go anywhere.

All components need to use a consistent `semconv` version or OTel
will emit errors about "cannot merge resource due to conflicting Schema URL".
Switch to the appropriate semconv version, which requires dropping
usage of `httpconv`. Instead, the upstream HTTP client hooks are
used directly. (The lower-level functions are no longer exported by
OTel.)

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.
