[chore] Simplify the OTEL setup (#4110)

# Description

This simplifies our OTEL setup by:

* Getting rid of some deprecated things.
* Using `autoexport` and letting things get configured by the `OTEL_` environment variables.
* Removing all the unnecessary config options.

+Package log provides the OpenTelemetry Logs SDK.
+
+See https://opentelemetry.io/docs/concepts/signals/logs/ for information
+about the concept of OpenTelemetry Logs and
+https://opentelemetry.io/docs/concepts/components/ for more information
+about OpenTelemetry SDKs.
+
+The entry point for the log package is [NewLoggerProvider].
+[LoggerProvider] is the object that all Bridge API calls use to create
+Loggers, and ultimately emit log records.
+Also, it is an object that should be used to
+control the life-cycle (start, flush, and shutdown) of the Logs SDK.
+
+A LoggerProvider needs to be configured to process the log records, this is
+done by configuring it with a [Processor] implementation using [WithProcessor].
+The log package provides the [BatchProcessor] and [SimpleProcessor]
+that are configured with an [Exporter] implementation which
+exports the log records to given destination. See
+[go.opentelemetry.io/otel/exporters] for exporters that can be used with these
+Processors.
+
+The data generated by a LoggerProvider needs to include information about its
+origin. A LoggerProvider needs to be configured with a Resource, by using
+[WithResource], to include this information. This Resource
+should be used to describe the unique runtime environment instrumented code
+is being run on. That way when multiple instances of the code are collected
+at a single endpoint their origin is decipherable.
+
+See [go.opentelemetry.io/otel/log] for more information about
+the OpenTelemetry Logs Bridge API.
