This uses otel standard environment variables to configure tracing in
the daemon.
It also adds support for propagating trace contexts in the client and
reading those from the API server.
See
https://opentelemetry.io/docs/specs/otel/configuration/sdk-environment-variables/
for details on otel environment variables.

This enables picking up OTLP tracing context for the gRPC
requests.
Also sets up the in-memory recorder that BuildKit History API
can use to store the traces associated with specific build
in a database after build completes.
This doesn't enable Jaeger tracing endpoints from env
but this can be easily enabled by adding another import if
maintainers want it.

These were changes I drafted when reviewing 7c731e02a9,
and had these stashed in my local git;
- rename receiver to prevent "unconsistent receiver name" warnings
- make NewRouter() slightly more idiomatic, and wrap the options,
to make them easier to read.
