remove custom logger, use standard logging library

[lilyydu]

DO NOT MERGE

Previously, we had a custom logger available for customers. However, this didn't integrate very well with the general industry - other libraries and frameworks use python's logging library (e.g., fastapi, boto3, etc), and most developers are familiar with it. In addition, using the standard library is better for reliability, and requires less maintenance.

• updated to use module level logging throughout the packages (removed from constructors, dependency injections)
• kept the ConsoleLogger, but added a deprecation warning
• kept the LoggerDependencyOption, but added a deprecation warning
  - kept the EventEmitterOptions (though it only has a logger property)
  - kept the ConsoleFormatter and ConsoleFilter as an option for developers to use
  - added the NullHandler so that no logs will show up, unless configured by the developer (added to every package init file)
• updated common/README to explain how to setup and customize the logger
• removed mock loggers from tests
• regenerated the handlers now that logger is no longer a property

Pull request overview

This pull request migrates the Microsoft Teams SDK from a custom ConsoleLogger implementation to Python's standard logging library. This is a significant refactoring that aligns the SDK with industry standards and improves integration with other Python libraries and frameworks.

Changes:

• Replaced custom ConsoleLogger with module-level loggers using logging.getLogger(__name__) throughout all packages
• Removed logger from constructors and dependency injection across all plugins and components
• Added NullHandler to all package __init__.py files following Python logging best practices
• Added deprecation warnings for ConsoleLogger and LoggerDependencyOptions
• Regenerated activity handlers to remove logger property requirements
• Updated README documentation with comprehensive logging setup examples
• Refactored tests to use pytest's caplog fixture instead of mock loggers

two questions

• does app_oauth.py need to be migrated to logging.getLogger?
• do we plan to update the examples as well?

@corinagum

• does app_oauth.py need to be migrated to logging.getLogger?

good point! it's referencing the context logger so it technically works, but we should add it to the top level instead so developers can filter at a finer level

• do we plan to update the examples as well?

I already updated the examples!
