Fix DeprecationWarning of jsonschema
`jsonschema.draft4_format_checker` and also `jsonschema.FormatChecker.cls_checks`
are deprecated and DeprecationWarning appears every time so these make
logs a little dirty and also these attribute/classmethod will be removed
in the future.
Therefore `jsonschema.draft4_format_checker` should be replaced with
`jsonschema.Draft4Validator.FORMAT_CHECKER` and
`jsonschema.FormatChecker.cls_checks` should be replaced with
`jsonschema.Draft4Validator.FORMAT_CHECKER.checks`.
Eventually, DeprecationWarning for jsonschema will disappear with this
proposed fix.
