Subject: [PATCH] goa: Add support for certificate prompts
Since commit f5ee590e, it is not possible to access Nextcloud/ownCloud
shares with self-signed (or invalid) certificates. This is because
the mount operation is handled by GOA volume monitor and the prompt
to accept certificate is not shown. Let's update the volume monitor
to handle just passwords and show the prompt to the client.
Fixes: https://gitlab.gnome.org/GNOME/gvfs/issues/251
