[controller] Replace deprecated klogr.New with textlogger.NewLogger

[AleksZimin]

Description

This PR addresses a deprecation warning related to the logger initialization. The previous implementation used klogr.New, which is deprecated due to its outdated output format. The logger has now been updated to use textlogger.NewLogger as recommended. This change ensures the logger is initialized using a more current and supported configuration.

Why do we need it, and what problem does it solve?

Updating the logger initialization prevents potential issues caused by relying on deprecated methods. This change ensures compatibility with the latest logging standards and improves the overall stability of the logging system.

What is the expected result?

• The logger is now initialized with textlogger.NewLogger, eliminating the deprecation warning.
• Improved compatibility with the current logging framework.

Checklist

• The code is covered by unit tests.
• e2e tests passed.
• Documentation updated according to the changes.
• Changes were tested in the Kubernetes cluster manually.
