SWDEV-536287 - Detect SELinux mode and log error if enabled (#819)

* Detect SELinux mode and fail-fast

* Detect SELinux status by reading /sys/fs/selinux/enforce during initialization.
* Fix the verbose mode for HIP Stream events

* Add more information in the logs
Add information to the user about how to change the setting
