OpenTelemetry Flask Instrumentation

The OpenTelemetry Flask Instrumentation library provides automatic tracing for Flask applications, building upon the OpenTelemetry WSGI middleware to track web requests. It captures Flask-specific features like using URL rule patterns as span names and setting the `http.route` attribute. This package is part of the `opentelemetry-python-contrib` project, which generally maintains a monthly release cadence, and its individual packages are typically in beta status.
