Add Performance profiling

[cehartun]

As a developer
I want to add performance profiling to the Controller to measure the performance.

Reason (Why?)
Why do you want this feature? What goals should be achieved? Is your issue related to a problem?

We do not have values about the performance and the goal is to be able to track changes when code is adjusted. This should help solve performance issues.

Solution (What?)
Describe the suggested solution (Don't repeat the reason again)

Adding profiling via pyinstrument

Out of scope
Anything that is out of scope and shall not be implemented

Performance improvments shall be made in separate requests

Relation to other Issues
Provide additional context (link relevant issues)
#538

Acceptance criteria
Describe acceptance criteria for testing (Don't repeat reason and solution again)

• pyinstrument is added as a library
• a report is generated with metrics about the performance of different functions
• the analysis should be toggable via a feature flag
