Is your feature request related to a problem?

I would like to have socket options applied before a connection is made so that they apply to handshake packets (e.g. IP_TOS, IPv6_TCLASS ).

Describe the solution you'd like

aiohappyeyeballs v2.5.0 now receives a "socket_factory" parameter (callback that returns a new socket) that allows a user to perform their own socket creation before each connection.
aio-libs/aiohappyeyeballs@v2.4.8...v2.5.0

I would like TCPConnector's constructor to offer a similar optional parameter so this functionality can be used. I propose that a "socket_factory" parameter replaces the recent "tcp_sockopts" parameter.

Describe alternatives you've considered

The existing tcp_sockopts could be repurposed for this, however, passing in socket options like this doesn't allow one to set different options depending on the destination address (e.g., IPv4 vs IPv6).
