Title: Add /_cat/fielddata to display fielddata usage

Currently has a disabled REST test, I'm not yet sure why the regular expression doesn't match.

The output is a little different because it has a dynamic number of columns depending on the number of fields, so if anyone has an alternative output format suggestion that would be great.

Closes #4593
