[Uptime] Filter bar missing Name. Values for ID/URL make little sense

[andrewvc]

As @jamiesmith pointed out we seem to be missing monitor names in the filter bar dropdown (see SS below).

This is a bug and a regression strictly speaking, however I don't believe it ever made sense to show a list of names there. It would only correspond to the name column of the larger list below. The same goes for ID and URL. Filtering by items with a cardinality of 1 doesn't make a lot of sense.

The real utility of these items in the filter bar is that using their search boxes is easier than typing/remembering monitor.name:"my name". To that end I propose we stop showing values in the dropdown for everything but port and type which are actually enumerable and have many monitors to a single value, and just use the others for their search boxes.

I'd propose that we show the search boxes for these fields, and let users input arbitrary strings there to add to the query. This probably dovetails with the Kuery bar work @jasonrhodes is working on. I'd very much appreciate your opinion here @jasonrhodes given that.

I had a quick chat with @andrewvc and we decided to drop filters for name, ID and URL for now as there is a PR that will solve this anyhow: #41588
