Single region high node count test

[danthegoodman1]

Say 3 replica groups, 10 nodes per group, all gossiping.

I would like to write a test that focuses on high node counts within a single region, with large replica groups. This is a more realistic test as regions don’t talk to each other, so we can test how requests are distributed in a high-density scenario.

Based on testing this behavior on my laptop, I have no doubts about the abilities of FS to delegate requests, manage partitions efficiently as they are remapped, and keep low latency (this was all thoroughly tested through development as I wrote it).

The major test is to see how gossip might behave (the code I did not write) at this scale, and how we might need to expose/tune settings, manage buffers, or switch to something like serf.
