query: /graph unusable on large __name__ set due to autocomplete

[clhain]

thanos version: 0.11.0

We run a query instance that has a very large set of unique metric names (we're working to reduce them). Attempting to use the GUI at /graph causes the browser to go unresponsive for a long time as it grabs the list of values (a few seconds) and then renders the dropdown (a few dozen seconds). During that time the window is unresponsive.

Grafana helpfully disables the autocomplete feature on large sets, is it possible to do something similar here?

There is this: #2150. Just need someone to follow up and rebase on master.

@clhain can you check if it's still a problem with the new React UI? We limit the dom rendering to 100 items at max, so it's shouldn't be a problem now.
