Mentioning of not allowing unescaped slashes in path parameters.

[dumka]

According to this discussion #892 unescaped slashes are not allowed in path parameters. But OpenAPI itself doesn't mention it. Is possible to add it to the specification in order to avoid any further confusion?

@dumka I took a swing at this over here. #2218

Closing as #2218 was merged. Thanks all.
