Revert "Maximize the number of parallel processes for processing & uploading perf data"

This reverts commit a92b95bb53e21fc4874ab3b8b1833fe3b990e3b0.

Reason for revert: suspect this causes dashboard internal error. 
BUG: chromium:873102 

Original change's description:
> Maximize the number of parallel processes for processing & uploading perf data
> 
> A big portion of perf data uploading latency is due to I/O operation (uploading),
> hence maximize the number of parallel processes to improve the wall-time.

If you go to https://chromeperf.appspot.com/ you'll see the error "ImportError: cannot import name gae_ts_mon". Reverting https://chromium-review.googlesource.com/c/catapult/+/1170043 and re-deploying.

Since the revert will take a while to submit, temporarily patched in a CL that comments out the ts_mon lines in dispatcher.py and re-deployed. Dashboard is up and running now. Lowered to P2 since dashboard is up.

Reassigning to benjhayden@ to reland the change safely and lead the postmortem (should cover dashboard push process, testing of changes to dispatcher.py)

Ah thanks Annie!

For posteriority, I will not reland #1 because that didn't seem to speed up perf uploading (it actually slow things down a big) 

#1 was not intended to speed up the perf dashboard. It was intended to reduce the error rate. Whether or not it stays landed should be based on the logs for whether machine instances are allocated better. I'll leave it to Ethan.
