add enable toggle, let operators have many configuraitons

this commit is a bit of a jumble, but it allows us to disable
a configuration so the associated deployment can in principle be
garbage-collected, and allows operators to have multiple configurations.
it also (as a temporary hack) ties the deployment subdomain to the username so it's clear to
operators where we're deploying to.
