Use singleton EventBasePool in ServiceRouter

Summary:
Switching ServiceRouter code to use VirtualEventBase instead of EventBase allows us to have same thread-pool shared between multiple ServiceRouter instances.

In future this allows us to replace EventBasePoolImpl with some generic thread-pool implementation (e.g. IOThreadPoolExecutor). It also makes it trivial to have ServiceRouter run on a any existing thread-pool if necessary.
