Pull Request Overview

This PR adds support for custom log record processors in the Azure Monitor OpenTelemetry distro. Users can now pass a list of LogRecordProcessor objects via the log_record_processors parameter to configure_azure_monitor(), allowing for custom processing and enrichment of log records before they are exported to Azure Monitor.

Key Changes

• Added log_record_processors parameter to configure_azure_monitor() configuration
• Custom log record processors are now added to the logger provider before built-in processors (quickpulse and performance counters)
• Included a sample demonstrating how to use the feature to enrich logs with operation name from the current span context
