OpenTelemetry DBAPI Instrumentation

The `opentelemetry-instrumentation-dbapi` library provides OpenTelemetry tracing for Python applications interacting with databases via libraries that adhere to the Python Database API Specification v2.0 (PEP 249). It's part of the `opentelemetry-python-contrib` project, which typically follows a monthly release cadence. The current version, `0.61b0`, signifies that it is still in beta, and while functional, its API or behavior may be subject to change. This instrumentation offers core functionality for database tracing, and while users often prefer framework or ORM-specific instrumentations, it can be used directly when those are not available.
