Cherry-pick of PR #5150 to 6.0 branch. Original message:
Requires: #5148
Enable flush based memory queue by default:
Increases chance of pushing bigger batches of events to the outputs.
Especially if number of CPUs is limited to 1 or 2 this helps with
throughput, as outputs and producers go-routines will interleave less.
Set flush.events=2048 and flush.timeout=1s
