Adding address unit attribute to queries

Hi @sweco-semhul! 👋 Thank you so much for this awesome PR (and the other corresponding ones). We are really excited about this feature and have talked about prioritizing very recently so this is great timing!

We'll have a look at the code very soon and get back with feedback, but at first glance, it looks great.

In order for this functionality to actually work in production we'll need to update our openaddresses importer to stop throwing away unit information. Currently we do not store unit numbers in our Elasticsearch schema so these new queries wouldn't be able to find much just yet.

@dianashk thanks for your kind words, happy to help!

As you have probably already seen, mentioned in the main issue, there are corresponding changes for that in schema pelias/schema#258 and the openaddresses importer pelias/openaddresses#320

Yes data needs to be reloaded and there were a lot of parts that needed to be touched to make this change and it is/was a bit tricky to test the full change.

Let me know if I can be of any help getting this further.

This looks good and worked for me with Portland addresses :)
