Nextcloudcmd: add support for Tor via socks5 proxy

[iootaa]

Hi there,

Expected behaviour

I'm trying to use nextcloudcmd with Tor. For that, I need use a socks5 proxy:

nextcloudcmd --logdebug --httpproxy socks5://127.0.0.1:9050 /home/amnesia/Persistent/nextcloud https://server.name

Actual behaviour

I get the following error message:

[ info nextcloud.sync.accessmanager ]: 2 "" "[...]/ocs/v1.php/cloud/capabilities?format=json" has X-Request-ID "4d7dd[...]"
[ info nextcloud.sync.networkjob ]: OCC::JsonApiJob created for "[...]" + "ocs/v1.php/cloud/capabilities" ""
[ warning nextcloud.sync.networkjob ]: QNetworkReply::NetworkError(UnknownNetworkError) "Error communicating with HTTP proxy" QVariant(Invalid)
[ info nextcloud.sync.networkjob.jsonapi ]: JsonApiJob of QUrl("[...]/ocs/v1.php/cloud/capabilities?format=json") FINISHED WITH STATUS "UnknownNetworkError Error communicating with HTTP proxy"
[ warning nextcloud.sync.networkjob.jsonapi ]: Network error: "ocs/v1.php/cloud/capabilities" "Error communicating with HTTP proxy" QVariant(Invalid)
[ debug default ] [ main(int, char**)::<lambda ]: Server capabilities QJsonObject()
Error connecting to server

(I just removed the timestamp and server name)

I've noticed that the default setting on the desktop app is to use the System Proxy, however, this does not actually work when that system proxy is Tor. This may be a separate ticket, but more general Tor support would also be highly appreciated.

Edit: #901 is the ticket described
