Merge branch 'bazelbuild:master' into c445

Merge pull request #1 from c445/fix-docker-tag-issue

adjust rules_docker to accomodate for containerd image sync

Do not add --all_incompatible_changes to presubmit (bazelbuild#662)

The incompatible changes is a little bit more involved than this, we
allow creating new incompatible flags which we don't expect users to
migrate for right away. The principled place to look for incompatibel
changes is to go to https://github.com/bazelbuild/bazel/issues?q=is%3Aissue+label%3Aincompatible-change+label%3Amigration-ready,
ideally also filtered with the bazel version (e.g. for flags that should
be migrated in bazel 0.22.0, add the label 'migration-0.22'.

On the buildkite, this is the pipeline that tells rule owners which
incompatible flags they have to migrate for in the current bazel
release: https://buildkite.com/bazel/bazel-at-release-plus-incompatible-flags

Properly set `cmd` from `args` in lang images. (bazelbuild#624)

Adding Basic Support for Windows Docker Images (bazelbuild#493)

container_import
Added a parameter called “manifest”. This allows Bazel to import a Windows base image without checking in GBs of tar files. All that is needed is the config and manifest files from the base Windows image. The layers parameter should be an empty list.

container_import(
name = "windowsservercore_1803",
config = "windowsservercore.1803.config.json",
manifest = "windowsservercore.1803.manifest.json",
layers = []
)

container_image
Added an optional parameter to docker_build called “operating_system.” While most of the changes are foreign layer specific, two changes were required to address Windows specifically.

There is no support for adding registry diffs, but diffs in existing layers will be respected and continue to work.

container_image(
name = "basic_windows_image",
base = ":import_windows_base_image",
cmd = ['bar.exe'],
files = [":bar.exe"]
operating_system = "windows",
)

* Adding basic support for Windows Docker images.
Does not support adding new registry delta's, but will work with
base images that already have registry deltas.

* Changing container_import to use
application/vnd.docker.distribution.manifest.v2+json instead of
application/vnd.docker.distribution.manifest.list.v2+json as the input.

* Using archive.py from http_archive.  To be removed when bazel 0.17,0 is released
