Some server class attributes are missing in socketserver docs

Documentation

While working with socketserver recently I noticed that the allow_reuse_port class attribute is not documented but the allow_reuse_address attribute is.

cpython/Lib/socketserver.py

Lines 185 to 198 in f9a5a3a

	Class variables that may be overridden by derived classes or
	instances:
	- timeout
	- address_family
	- socket_type
	- allow_reuse_address
	- allow_reuse_port
	Instance variables:
	- RequestHandlerClass
	- socket

In addition there's a couple of places we could clean up right now, for instance address_family is still grouped with the per-instance attributes rather than the class attributes, request_queue_size is only applicable to TCP, and there's another missing undocumented class attribute for specifying max packet size that is only applicable to UDP.
