What does OTEL_PYTHON_CONFIGURATOR refer to in the docs?

Hi, I'm implementing OpenTelemetry in a Python application and the Instrumentation tooling has been really useful. In the docs there's a mention of an OTEL_PYTHON_CONFIGURATOR environment variable. I can find this mentioned in code here but i can't find any definitions as to how to write a configurator or what the purpose of one is.

Does anyone know where i can find documentation of the OTEL_PYTHON_CONFIGURATOR environment variable and how to use it?
