Description of the problem including expected versus actual behavior: There are filters on spy panel in discover!!!

Filtering in for a value works on them. But filtering out does not. As a result you actually get stuck and cannot go back to looking at all values for that index pattern on discover.

Same bug in 5.3.1. So this is not a regression.

Steps to reproduce:

1. Load Logstash(any time-series data) index pattern and open it in discover
2. Open spy panel
3. Click on filtering in on that value which works fine. But when you filter out - it doesn't work. You actually are stuck in there and the only way out is clicking on browser's back button. Also the filter controls don't show up as they do elsewhere when you use them.

I'm guessing this is due to the changes in #9989. I'm not sure whether we should keep the filter buttons and make them work in the spy panel, or get rid of them from the spy panel.

@Bargs Any reason we wouldn't want to keep them in the spy panel?

The only thing I can think of off the top of my head is that more things in the spy panel will be un-filterable, so it might be confusing.

For instance, none of these columns are filterable for the tilemap:

It might not be obvious to a user why the filter icons don't show up here, but they do for a timestamp field, for instance. We already hide the filter icon in non-filterable columns so it's not like it'll break anything, but it just might be confusing.

This seems to be working fine now, I think it may have been fixed by #11628

Reopening this as this isn't working in 5.5.0 BC
