Related to #6273

The version of Redis that ships with Ubuntu Trusty is too old to support

this, but it seems a lot easier to just use the latest Ubuntu LTS
release (i.e. xenial), which has a recent-enough Redis in its archives.

not relative. Unfortunately, the domain used to build such URLs is the wrong
one: LOCAL_DOMAIN, and not WEB_DOMAIN, where the assets are stored.
