Adding performance tests

Breaking change

Proposed change

This PR adds simple performance tests for NetDaemon. For now it is not able to run as part of the CI/CD pipeline but can be run locally.
This is something that will be added in the future.

It adds a performance test server that fakes HA and a NetDaemon client project that contains apps that meassure and logs performance.

The PR also adds a small fix to HomeAssistantConnection that I found when writing the performance tests.
