[BUG] Reduce noise from Qualx logs

[amahussein]

Describe the bug

The qualX generates some log warnings that make it more difficult to spot errors/warnings in the tools output.
These warning are generated for each app which makes the log a little bit noisy.

For example the message below, it does not really help because it has no information about

Steps/Code to reproduce bug

We like to improve the readability of the logging by either making those messages more concise or by revisiting them and deciding on what exactly to report.
