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.

Most commands use either a kind, or a more readable spelling of a
kind, in their output. To make this easier, this centralises the
definition of those names in one place, and lets the command
implementations choose whichever they need.
