As a user, I want a reliable source of address autocompletion to help me pick a valid address.

Acceptance criteria:

• Provide at most X number of address candidates (X being configurable).

Going to re-open this. I think we've been misusing the findAddressCandidates endpoint. From the description:

The findAddressCandidates operation geocodes one location per request

It is meant to transform a well formed address into a point or polygon. We are using it for this, but we're also using for auto-completion. It's not very good at this. Here's a quick gif of my making multiple requests w/ insomnia - you can see it cuts out in the middle, and only gives me useful auto completions once I've correctly typed in most of my address:

Something like the Google Autocomplete API is purpose built for this, and should be used instead (plus it comes w/ a nice widget). In the meantime, we should disable auto-completion and just have an error message that says "We couldn't find your address" or something.

Should be merged with #28 per pending changes to API via PR #47

Just want to note that whatever we build, we'll need to provide the coordinates the our autocompletion API resolves to using Web Mercator coordinates (wkid 3857),
