Description:

To use Synapse's URL preview feature, the optional dependencies only mentions the `python2-netaddr` package. However `python2-lxml` is needed as well but isn't listed.

Additional info:
* package version(s): 0.22.1-2

Steps to reproduce:
* Install the package (and generate the configuration as prompted) and all of its optional dependencies
* Turn `url_preview_enabled` to true in the configuration
* Try starting the `synapse` systemd service. A `systemctl status synapse` will show it failed to start with this error: `Missing lxml library. This is required for URL preview API.`

Installing the `python2-lxml` solves it, but it would be nice not to have to crash Synapse to realise that the package is required for this feature.
This task depends upon
