[Workbench] Log tab takes too long to load with large logs

Description
With a very long running pipeline, like tb05z-d1hrv-lx5w1pngtl2poj9, when you click on the "Log" tab, it spins for a while and then fails with "504 Gateway Time-out". Presumably workbench is loading too much logs and it is taking too long.

This pipeline instance is still running as of this writing, so far running for 1 day and 14 hours and 5+ minutes. So far it has 100327+ log lines.
Workbench is trying to retrieve all of those lines and eventually timing out.
I now am limiting the number of log lines fetched to 2000. Now I see the log, with the newest 2000 log lines. And since the pipeline is still running, I am seeing log roll with newer lines from event log.
I was also able to see the log successfully using a limit size of 10000; however, in this case, fetching those many log lines took more than a minute. I hence feel that it is better to get less number of rows than make the user wait longer.
