OpenAPI: Fix nova examples

When generating the nova AZ detail schema we are adding examples to the
`hosts` object, but we are doing it wrong:

- We are adding a dictionary instead of a list, which is what the plural
  form of example indicates and also what we can see in the OpenAPI spec
  documentation [1].

- The contents of the example are wrong, it shouldn't have the `JSON
  request` key, as we can see in the upstream docs [2].

This patch fixes the examples to be correct.
