QA/v1: Run 200-nodes test for final report with latency emulation

[hvanz]

This is essentially the same 200-nodes test for the v1 release as described in #2461 but using the latency emulation feature of the e2e framework.

Settings:

• Run on v1.x branch.
• Vote extensions enable height: 1
• PBTS enable height: 1
• Run two sets of experiments:
  1. for discovery of the saturation point (mainly because with latencies the saturation point is likely to be different)
  2. to gather metrics on all nodes using a load slight below the saturation point
• Duration ~40 mins
• With latency emulation enabled by randomly assigning "zones" to all nodes.

DoD:

• On the final QA report for v1, a section for the 200-nodes test with latency emulation, so we can use a baseline for comparison with future releases, where the 200-nodes test without latency emulation will be deprecated.
• The report should contain three subsections:
  • saturation point discovery,
  • metrics report for the discovered saturation point, and
  • a comparison between the new metrics with the metrics obtained in QA/v1: Run 200-nodes test for final report without latency emulation #2461.
