Since PyYAML 5.1, yaml.load without specifying the Loader option is deprecated and shows the following warning. YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details. This change replaces usage of yaml.load by yaml.safe_load, to get rid of that warning message. Change-Id: Ibe25c4aaf3aa7226f28ec60b8a929ecc143face1
