Create automated benchmarks for main usecases

[marcmo]

We need to track the performance for our main usecases:

• search in text file
• open dlt file
• search in dlt file
• startup measurements
• open 100 sessions for small files at the same time
• shutdown measurements

This should run in our own environment (custom github runners).
That way we can run the tests on our testdata that we store on the test-instance.

usage

• should be integrated in build-system
• should be get executed by tester offline (not on github actions) or in relative constant CI environment

Already Implemented :

• search in text file
• open dlt file
• search in dlt file

In progress :

• startup measurements
• shutdown measurements
• open 50 sessions for small files at the same time

To be implemented :
Dmitry will create an issue for:
concat view: disable button "open as single" for more than 50 files
concat view: notify user with popup about opening as single tab more than 10 files
sys level (client) - prevent more than 50 tabs/session. Ask user close some tab with attempt to open +1 over 50 opened
rust level - return error on session-create-request if it's +1 over 50
