This removes the need for the core context code to import
`github.com/docker/cli/cli/context/kubernetes` which in turn reduces the
transitive import tree in this file to not pull in all of Kubernetes.
Note that this means that any calling code which is interested in the
kubernetes endpoint must import `github.com/docker/cli/cli/context/kubernetes`
itself somewhere in order to trigger the dynamic registration. In practice
anything which is interested in Kubernetes must import that package (e.g.
`./cli/command/context.list` does for the `EndpointFromContext` function) to do
anything useful, so this restriction is not too onerous.
As a special case a small amount of Kubernetes related logic remains in
`ResolveDefaultContext` to handle error handling when the stack orchestrator
includes Kubernetes. In order to avoid a circular import loop this hardcodes
the kube endpoint name.
Similarly to avoid an import loop the existing `TestDefaultContextInitializer`
cannot continue to unit test for the Kubernetes case, so that aspect of the
test is carved off into a very similar test in the kubernetes context package.
Lastly, note that the kubernetes endpoint is now modifiable via
`WithContextEndpointType`.

Previously an endpoint registered using `RegisterDefaultStoreEndpoints` would
not be taken into consideration by `resolveDefaultContext` and so could not
provide any details.
Resolve this by passing a `store.Config` to `resolveDefaultContext` and using
it to iterate over all registered endpoints. Any endpoint can ensure that their
type implements the new `EndpointDefaultResolver` in order to provide a default.
The Docker and Kubernetes endpoints are special cased, shortly the Kubernetes
one will be refactored to be dynamically registered.

I'm about to refactor the code which includes the Kubernetes support in a way
which relies on something vendoring `./cli/context/kubernetes/` in order to
trigger the inclusion of support for the Kubernetes endpoint in the final
binary.
In practice anything which is interested in Kubernetes must import that package
(e.g. `./cli/command/context.list` does for the `EndpointFromContext`
function). However if it was somehow possible to build without that import then
the `KUBERNETES ENDPOINT` column would be mysteriously empty.
Out of an abundance of caution add a specific check on the final binary.

The comment on `github.com/docker/cli/kubernetes.NewKubernetesConfig` said:
// Deprecated: Use github.com/docker/compose-on-kubernetes/api.NewKubernetesConfig instead
By making this switch in `github.com/docker/cli/context/kubernetes/load.go` we
break a vendoring chain:
`github.com/docker/cli/cli/command`
→ `vendor/github.com/docker/cli/cli/context/kubernetes/load.go`
→ `vendor/github.com/docker/cli/kubernetes`
→ `github.com/docker/compose-on-kubernetes/api/compose/...`
This means that projects which just want `github.com/docker/cli/cli/command`
(which is itself pulled in transitively by
`github.com/docker/cli/cli-plugins/plugin`) which do not themselves need the
compose-on-kubernetes API avoid a huge pile of transitive dependencies.
On one of my private projects the diff on the vendor dir is:
280 files changed, 21 insertions(+), 211346 deletions(-)

* `github.com/peterbourgon/diskv`
* `k8s.io/api/*` (_lots_ of subpackages)
* `k8s.io/client-go/{discovery,kubernetes/scheme}`
and I've gone from:
$ du -sh vendor/k8s.io/
8.1M vendor/k8s.io/
to:
$ du -sh vendor/k8s.io/
2.1M vendor/k8s.io/
(overall I went from 36M → 29M of vendor dir for this particular project)
The change to `cli/command/system/version.go` is just for consistency and
allows us to drop the now unused alias.

This regressed in 3af168c7df ("Ensure plugins can use `PersistentPreRunE`
again.") but this wasn't noticed because the helloworld test plugin has it's
own `PersistentPreRunE` which has the effect of deferring the resolution of the
global variable. In the case where the hook isn't used the variable is resolved
during `newPluginCommand` which is before the global variable was set.
Initialize the plugin command with a stub function wrapping the call to the
(global) hook, this defers resolving the variable until after it has been set,
otherwise the initial value (`nil`) is used in the struct.

With this patch it is possible to alias an existing allowed command.
At the moment only builder allows an alias.
This also properly puts the build command under builder, instead of image
where it was for historical reasons.
