Support for dynamic backend healthchecks.

Adds support for healthchecking on dynamic backends, much as there is
the existing support for healthchecking for static backends. The main difference
being that with dynamic backends, there is a rate limit applied to the number
of healthchecks per sid you can create to prevent ill-use. A rate-limited
healthcheck will return an error on healthcheck() or on dynamic backend creation.
