Replace glog with klog

[lucasfcnunes]

Description

It seems that this idea is not new 9f10a87. The most obvious feature is the possibility to easily change logging format from text to json.

Summary

glog:

• Developed by Google.
• Provides leveled logging (INFO, WARNING, ERROR, FATAL).
• Not actively maintained anymore.

klog:

A fork of glog created by the Kubernetes community.

• Actively maintained and developed.
• Designed to address issues in glog, especially in containerized environments.
• Offers better support for structured logging and context.

In essence, klog was created to overcome the limitations of glog, making it more suitable for modern applications, especially those running in Kubernetes.
