Add simple flow test of beekeeper

This MR will related to hive#561 (closed) and hive#562 [Edit]

I changed to draft, because simple_flowe tests are a little bit unstable, and sometimes fail. I need to inspect why this happens.

Done

[Edit 13.02.2024]

After today's talk, we decided to set this issue on hold and wait till the implementation of a dedicated beekeeper module that will handle multiple beekeeper sessions.

[Edit 14.02.2024]

I will adjust those test to use just single session. In future we will extend it by using multiple sessions.
