Description of problem:
Recently introduced by the following python-rhsm commit is a new/optional configuration for [server] server_timeout that should be described in the man page for rhsm.conf provided by the subscription-manager package.

    Commit: 5780140650a59d45a03372a0390f92fd7c3301eb
    Allow users to set socket timeout.
    Remove the old method of setting a universal timeout (which was required 
    due to limitations in Python versions that we don't support any more) 
    and instead specify the timeout on a per-connection basis.

You will now see it as an available configuration in...

[root@jsefler-rhel7 ~]# subscription-manager config

   hostname = jsefler-candlepin.usersys.redhat.com
   insecure = [0]
   port = 8443
