This should prevent the generation of the object getting bumped, as
observed on a GKE K8s 1.18 cluster using the logic before this commit.
We only want to generation to increase when there are actual changes to
the `spec` of a resource, as some controllers use the `generation`
value to make assumptions about what they should do during a
reconciliation.

controller-runtime methods now accept `client.Object` and
`client.ObjectList` rather than `runtime.Object`. This means the
adapter interfaces need to change signature, but happily, little else.
Since the list adapter is now distinct to the object adapter, `len()`
can go there instead of the command-specific interfaces.

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.

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 adds a command for deleting ImagePolicy objects. Since the
control flow for the command needs only a runtime.Object (and a name
for the type), it can be factored out.
I have made the argument (field in the deleteCommand struct) an
interface `objectContainer`, through which the command code gets a
`runtime.Object` to deserialise into (and delete). It could be simply
a `runtime.Object` here; however things like `getCommand` require
other methods, so it's convenient to have an interface for it.
