    Replace yaml.load() with yaml.safe_load()

    Avoid dangerous file parsing and object serialization libraries.
    yaml.load is the obvious function to use but it is dangerous[1]
    Because yaml.load return Python object may be dangerous if you
    receive a YAML document from an untrusted source such as the
    Internet. The function yaml.safe_load limits this ability to
    simple Python objects like integers or lists.

    In addition, Bandit flags yaml.load() as security risk so replace
    all occurrences with yaml.safe_load(). Thus I replace yaml.load()
    with yaml.safe_load()
