Example needs a separate README

[sobolevn]

Currently, it is unclear how to use example/, because there's no information available.

Looks like it needs its own guide:

• How to install all the required dependencies?
• How to run the project?
• What should you expect?
• How to simulate the high-load so I can test that the metrics work?

Thanks, we will implement the suggestions you mentioned above as soon as possible.
