URL formatter file:// URI support

[upkeihas]

Currently Kibana does not support file:// URIs. if you have a field whose type is URL and you try to use it for local file links, it will not work. (See https://discuss.elastic.co/t/make-a-file-link-clickable-in-a-visualisation/124105)

By default the links will be of the format http://kibanahost/app/file:///path/to/file, which obviously does not work. Also it's not always possible or even sensible to use a http server to serve local files, or files that are available as a network share.

For example, if I analyse a bunch of log files and store the path to the log file in an event, I would like the path to be a clickable link that opens the said log file without the need to use a http server.

Apparently this has worked before, no idea who thought to remove it. (See https://discuss.elastic.co/t/kibana-url-format-bug-file/121414/2

It worked in 5.x . Ideally the url format option should support any valid URI per the RFC.

I just want to leave here the same information than on #16983 (comment): File links won't work in any modern browser from http(s) pages, due to security restrictions.

I will actually close this as a duplicate of #16983 If you feel this issue is asking for something else than that other issue, please feel free to clarify for me on that, we can then reopen that issue.
