[issue33540] socketserver: Add an opt-in option to get Python 3.6 behaviour on server_close()

[STINNER Victor]

New submission from STINNER Victor <vstinner at redhat.com>:

bpo-31151 changed ForkingMixIn and bpo-31233 changed ThreadingMixIn to block on server_closer() for processes/threads.

I propose to add a new opt-in option to get the Python 3.6 behaviour. The old behaviour was wrong, but I expect that some people rely on it.
