94ec6a7506 kubernetes: Re-add k8s-dns-{sidecar,kube-dns,dnsmasq-nanny}-amd64 to cache
These were removed as unused in 8acecf1b62 but with the update to 1.7.2 they
are now pulled in (again?) by the default system.

8acecf1b62 kubernetes: Drop k8s-dns-* from image cache
These contribute ~140M to the common image cache but do not appear to be used
by either the base system nor the sock-shop demo. They can/will still be pulled
on demands as necessary.

d5bcb62419 kubernetes: Bump to 1.6.7 and other updates
Bumps kubernetes and associated tools and images to v1.6.7 (from v1.6.1).

Updates weave from v1.9.4 to v2.0.1

Updates cni from a snapshot to v0.5.2. Note that the download location has
changed and the tarball no longer includes the `bin` subdirectory, so adjust
build to compensate.

87a6e19770 kubernetes: add "show-tags" target to image-cache
Apart from adding the recursive target itself this required:

- Unescaping the @ in the image names, this was confusing `make` into always
  rebuilding and wasn't necessary (I had previously thought I had seen oddities
  due to these being interpreted by the `patsubst`, but I think that was just the
  colons.
- Making the recursive rules silent (prepending an @), those command lines are
  not especially enlightening and they obscure the output in the show-tags case.

With this the output is like:

    $ make --no-print-directory -C image-cache/ show-tags
    linuxkitprojects/kubernetes-image-cache-common:94a0715c6b3604e909bc0da74260dc7f1142d90d-dirty

4b030f2fc6 kubernetes: use digests for cached images
This ensures rebuilds will always get the same things.

56a8d2468a kubernetes: modernise image cache builds
This updates the build of the two image caches to use the `pkg/package.mk`
infrastructure, albeit in a slightly (ok, very) atypical way.

In order to share the bulk of the build code (including the `Dockerfile` and
the `Makefile` machinery to download the images) we arrange for the necessary
bits to be copied at build time into distinct subdirectories and for the
`pkg/package.mk` to be aware of this possibility.

Since pkg/package.mk is only set up to build a single package we use a single
`image-cache/Makefile` to drive the whole process and recurse into
`Makefile.pkg` to build individual packages.

One particular subtlety is that the package hash is based on the `image-cache`
directory (which is in `git`) rather than the generated subdirectories (which
are not in `git`). Since all the generators (and their inputs) are in the
`image-cache` directory this is what we want. This means that the two images
are given the same tag, but this is deliberate and desirable.

The generated directories are completely temporary to avoid picking up stale
versions of images when versions are updated. Images are hardlinked into place.

The images are moved to the linuxkitprojects org. Using a dev tag for now, will
update once everything is in place.

Also use "tag" rather than "build" where appropriate in the Makefile.

There is no point in the .dockerignore now, but add a .gitignore.
