Add possibility to modify conditions for flaky tests

[p-nikolaichik]

I found info in documentation of allure:
The Flaky mark is automatically added to a test if all the following conditions are met:

• the test got the Failed status at some point within the latest 5 launches,
• the test got the Passed status at least one time since then,
• the test got the Failed or Broken status in the latest launch.

Is it possible to modify these conditions somehow?
