Disable connection reuse for WebSocket connections in Apache

[skateman]

This is a temporary workaround for the issue described here:
https://bugzilla.redhat.com/show_bug.cgi?id=1404354

This can be reverted after httpd is updated to 2.4.25 or newer

@bdunne We will also need to add this for containers here

[jrafanie]

@skateman This is nitpicky but it looks like you can use on (lowercase) so it's consistent throughout this

Sorry. 🏃

[skateman]

@jrafanie fixed

Everything looks fine. 🍪

👍 LGTM

... disablereuse=on ¯\_(ツ)_/¯ naming is hard

[gtanzillo]

Nice! 👍

[jrafanie]

Note, this will need @carbonin @bdunne help to backport since @skateman's first PR is probably what we'd need to backport. ManageIQ/manageiq-gems-pending#217

@skateman As per the comment above, please create a separate PR for Fine.

[skateman]

@simaishi are you sure about the separate PR for fine? As far as I remember the add_ports has been dropped earlier and we need my old gems-pending solution for euwe only. cc @jrafanie

[simaishi]

Since manageiq-balancer-websocket.conf doesn't exist in Fine branch, I'd assume we need the gems-pending PR for Fine/Euwe.

[skateman]

@simaishi here you go: ManageIQ/manageiq-gems-pending#219
And what about euwe?

[simaishi]

Can I just backport ManageIQ/manageiq-gems-pending#219 to Euwe?

[simaishi]

Backported to Fine via ManageIQ/manageiq-gems-pending#219

[simaishi]

Backported ManageIQ/manageiq-gems-pending#219 to Euwe.
