define segment size or time interval

[aruandre]

add the ability to define a segment size or time interval after which the .tmp file is rotated and events sent to output.

for example at the moment we have just a couple of mapping errors per day. the .tmp file is a few kb in size. with this rate you can calculate how long it would take until it reaches 10mb.
having to restart the pipeline on a daily basis in order to have dlq events ingested does not seem reasonable at all.

would be nice if the documentation also said anything about the segment size limitation.
