DAV Push ignores system Proxy

[mtdcr]

Hi everyone! Thank you for all your work on DavX5 and WebDAV in general!

I just tried this extension with the Conversations UP provider, but it failed to connect. This is because it didn't attempt to use the configured HTTPS proxy server. So the outgoing connection was refused by the firewall. The other parts of my Nextcloud installation work fine within this setup (installing updates or extensions, for example).

Here's the error message I observed:

transport web-push failed to deliver notification to subscription 1. error message: file_get_contents(https://up.conversations.im/push/v2.local.[...]): Failed to open stream: Connection refused

The proxy gets set in config.php:

<?php
$CONFIG = array (
  'proxy' => 'proxy.internal:8080',
  [...]
);

It would be nice if this could be supported in a future version, in order to support more secure setups.

Hi! Thanks for your report. Would it be possible for you to create a PR with the suggested changes?

I'm not a PHP developer and chronically short of time "lately". I might come up with a patch in the distant future, but if anybody else who knows better how to solve it comes first, I wouldn't be unhappy.

I'd guess there should be a reusable function in Nextcloud. But I never attempted to write an extension for Nextcloud, so I have no idea really.
