[7/n] [reconfigurator] combine inventory and omicron zones (#6739)

Currently, when the collection process makes two separate queries to
sled-agent: one to obtain basic inventory, and the other to obtain
Omicron zones. With this approach, it is possible for one of the two
queries to fail -- in that case, the `sled_agents` and `omicron_zones`
maps will not have the same set of keys.

In general, consumers of collections must be able to handle these kinds
of failing cases, because collections contain information from a variety
of sources, not all of which are guaranteed to work all the time. But
this specific case (sled-agent inventory vs Omicron zones) is not
intrinsic to the system -- it is an artifact of our APIs.

Change the API so that the `/inventory` endpoint also returns Omicron
zones. The format remains the same, so that `PUT /omicron-zones` mirrors
`GET /inventory | jq .omicron_zones`.

I had to make a few changes to our tests, since we now have a unified
notion of Omicron zones and sled agents. But this exposed what feels to
me like a modeling deficiency in the way our tests work. I hope to fix
that up at some point soon.

There is also one behavior change to the reconfigurator CLI -- now,
`inventory-generate` preserves zone information passed into it from the
system. This matches the behavior of inventory generation within tests
themselves.
