Subject: [PATCH] Async batch implementation
Add find_job checks
Check if should close on all events
Make batch_delay a request parameter
Allow multiple event handlers
Use config value for gather_job_timeout when not in payload
Add async batch unittests
Allow metadata to pass
Pass metadata only to batch jobs
Add the metadata to the start/done events
Pass only metadata not all **kwargs
Add separate batch presence_ping timeout
