Since the generic commands tend to share a few of the methods they
need -- at least AsClientObject -- it's worth having just one wrapper
struct for each API type, and adding methods to it where necessary.
For the automation types, I put these in auto.go.
While doing this I also did some tidying:
- I changed the name of the wrappers to `<type>Adapter`, and the
generic adapter to `universalAdapter` (it's only needed for delete,
so far).
- I de-exported and renamed some interface methods e.g.,
`exportItem`. They aren't needed outside the package.

This uses the established abstractions to implement the usual
subcommands for the ImageUpdateAutomation type.
I've called the sub-subcommand in each case `image-update`, as a
fairly safe shorthand for the much longer `image-update-automation`.
