Validate all passed values are a Array data structure
value does not pass the check.
Example:
These values validate
$my_array = [ 'one', 'two' ]
validate_array($my_array)
These values do NOT validate
validate_array(true)
validate_array('some_string')
$undefined = undef
validate_array($undefined)

unless arg.is_a?(Array)
raise Puppet::ParseError, ("#{arg.inspect} is not an Array. It looks to be a #{arg.class}")
