Title: Wire the service limits store into the diagnostics manager

This patch leverage's the functionality provided by the (cached) service limit store to supply configurable values for the event buffer size and the limit of explain files.

As an academic exercise, I've turned `ServiceLimit` into a fully fledged type, in order to make it self-describing and to help with avoiding bugs when passing lots of strings into function calls.
