All instrumentations packages have almost exactly same setup.py files.
This commit adds a python script that generates it from a source
template. This dramatically reduces the time and effort required to
update all instrumentation setup.py files, and also reduces chances of
making manual mistakes.
This commit adds a new logging instrumentation. The instrumentation
patches standard library logging module to inject tracing context
variables (otelSpanID, otelTraceID, otelServiceName) into log record
objects. It also optionally calls `logging.basicConfig()` and sets a
logging format that makes use of these vars if instructed by the user.
