prevent 502 errors caused by apache port-reuse (home-assistant#3267)

mjj4791 · fabaff · commit 44474e53424f · 2017-08-28T11:17:24.000+02:00
Without the 'disableeuse=On' configured, Apache will try to reuse tcp ports even when these ports were closed by home assistant (tcp FIN was sent). When Apache tries to use such a port, no answer will come from home assistant, causing Apache to respond with a HTTP 502 error.

With this option turned on, the situation will not occur (since ports will not be reused).
