Create a benchmark (memory/cpu) for different operations on a large heap

[bibaev]

It seems necessary to find out what operations we can afford to perform and when. Also it would be nice to monitor some performance metrics after significant changes. It would be cool to have a benchmark setup for some operations.

A possible solution is:

1. start idea headless
2. open a project (intellij-community, for example)
3. wait until the project will be imported
4. perform some operations on the memory agent side
5. create a benchmark report.
