Are we increasing the memory requirement for heapster pod as a whole?

Yes. Just in case.
For 1000 node cluster we are able to operate without any sink at 2-2.3gb (with 30k pause and 2k system pods). GKE http output creation consumes +400MB. That brings us to 2.75. If couple events occur at once: scraping, gke scraping and pod relist then the temporary memory consumption can be bigger. So to be on the VERY safe side I decided to go with 4 multpilier.

As we did a lot of noise (=events) during the tests it became apparent that Eventer should also have more memory. List that happens inside of watch consumes LOTS of memory (we will try to get rid of it just after 1.2).
