This should still mention the daemon thread, as that's more important.

You also need to change Python3

The daemon thread should be mentioned in start_http_server, as that's the primary docs the user will see.

This change allows each HTTP request to be served by a separate thread (I think!).
This came about because of a network issue, which was causing one Prometheus to keep a connection open - causing all other Proms to fail the exporter as they couldn't get a connection.
This is also consistent with the Go exporter behavior.
Cheers,
James
