Update to google/protobuf from 3.x to 4.x to get rid of the vulnerability. Also, other bug fixes and minor improvements. This release might change the log format, see #3505594 for more details.
Implemented pushing Drupal Logs to OpenTelemetry, switched to batch processing to improve performance, optimized span initialization and finishing process.
The main changes are renaming the "opentelemetry.tracer" service to just "opentelemetry" to be more clear, and reworking the initialization of the root span to catch more request types.
In this release I reorganized the initialization of the tracer to be more flexible. Also, added the opentelemetry_syslog module that adds the trace_id to syslog log records.
