It's a common pattern in the create commands to construct a value,
then (if not exporting it) upsert it and wait for it to
reconcile. This commit factors `upsert`, which does the update/insert
bit, and `upsertAndWait`, which does the whole thing.
Since these output messages, they are methods of `apiType` (previously
`names`), so that they have access to the name of the kind they are
operating on.
