* Add ctx to publish.Interface
I noticed that hitting ctrl-C didn't work when pushing images, this
should fix that.
* Use context everywhere that makes sense
* Refactor the publish.Namer to produce the full repo name.
* Add --naked to have image publishing use ${KO_DOCKER_REPO}:tag
* Change flag name, add disclaimer
* Create a MultiPublisher
MultiPublisher mimics io.MultiWriter in that it will publish an image to
multiple publish.Interface implementations.
* Add publish.{Tarball,Layout}Publisher
This adds support for publishing in the tarball format and to an OCI
image layout.
The tarball format isn't great, yet. It only supports writing once
instead of appending.
* Consolidate options
These were spread all over the place for no reasons. Now all the
publisher related options are grouped together.
* Add options for tarball/layout
Adds --oci-layout-path, --tarball, and --push flags.
--push=false will disable the default behavior of publishing to a
registry.
* go mod vendor
* Add Close method to publish.Interface
This allows us to defer writing to the tarball until we've collected all
the images that have been published.
* Fix tests
