Add support to validate list of items in json5 config.

Add support to validate list of items in json5 config.

Allow both forms of list validation in JSON5 config:
1. ensure list is exactly as specified (current)
parameters: {
  exact_list_param: {
    valid_type: "list",
    valid_values: [
      ["a", "b"],
      ["b", "a"],
    ],
  },
},
2. ensure each item in list is in valid_values (new)
parameters: {
  api_method: {
    valid_type: "list",
    valid_values: ["parseSingleValue", "parseShortHand"],
  },
},

Hi Anna,

As discussed, this simple improvement allows us to specify valid values for list
items in the config.

PTAL.

Thanks,
Kevin
