Remove yaml unsafe deprecation warning

hides warning such has below in the projects using config-probe.
This will make sure that config-probe uses the safe yaml load version.
I don't see a valid reason to have injected code in your configuration
ifile.

This is a possibly breaking change.

YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated,
as the default Loader is unsafe.

Please read https://msg.pyyaml.org/load for full details.
