zilencer: Change push bouncer API to accept uuids as user identifier. 

This is the first step to making the full switch to self-hosted servers
use user uuids, per issue #18017. The old id format is still supported
of course, for backward compatibility.

This commit is separate in order to allow deploying *just* the bouncer
API change to production first.
