Pull request overview

This PR adds extensibility to the configure_azure_monitor function by introducing two new parameters: log_processors and metric_readers. These allow users to provide custom log processors and metric readers alongside Azure Monitor's default processors/readers, following the existing pattern established by the span_processors parameter.

Key changes:

• Added LOG_PROCESSORS_ARG and METRIC_READERS_ARG constants
• Implemented default configuration handlers for the new parameters
• Integrated custom log processors and metric readers into the setup pipeline
• Added test coverage for configuration storage and defaults
