Consider pulling AsyncLightblueClient into lightblue-client from esbtools/event-handler #307
Description
Basically, to more efficiently process batches of events, we have an asynchronous client interface with an implementation which lazily performs all requests so they can be batched together in one call. I talked about with @jewzaam about this a few weeks ago and he suggested moving it to the lightblue client library since it is pretty general purpose.
Other implementations could use a thread pool, or whatever.
I don't expect many use cases where this would be essential though since most Java applications are handling requests within a preexisting thread pool. But it is useful for different concurrency models, like batch jobs.
