Using "--no-cache-dir" flag in pip install ,make sure dowloaded packages
by pip don't cached on system . This is a best practise which make sure
to fetch ftom repo instead of using local cached one . Further , in case
of Docker Containers , by restricing caching , we can reduce image size.
In term of stats , it depends upon the number of python packages
multiplied by their respective size . e.g for heavy packages with a lot
of dependencies it reduce a lot by don't caching pip packages.
Further , more detail information can be found at

`set -e` does not catch errors in bash command substituions like
`echo $(bad cmd)` so bazel thinks it succeeded and cached the result.

Will re-submit when ICMP dest unreachable is handled correctly and it can be
turned back on.

This rule isn't restored when the Kokoro VM is restarted, so it's not doing
anything. And the problem it was meant to solved is instead addressed by
https://github.com/google/gvisor/pull/3207.

The go.mod dependency tree for the shim was somehow contradictory. After
resolving these issues (e.g. explicitly imported k8s 1.14, pulling a
specific dbus version), and adding all dependencies, the shim can now be
build as part of the regular bazel tree.
As part of this process, minor cleanup was done in all the source files:
headers were standardized (and include "The gVisor Authors" in addition
to the "The containerd Authors" if originally derived from containerd
sources), and comments were cleaned up to meet coding standards.
This change makes the containerd installation dynamic, so that multiple
versions can be tested, and drops the static installer for the VM image
itself.
This change also updates test/root/crictl_test.go and related utilities,
so that the containerd tests can be run on any version (and in cases
where it applies, they can be run on both v1 and v2 as parameterized
tests).

We need docker IPv6 for ip6tables tests. Docker has spotty IPv6 support, so just
enabling IPv6 in daemon.json breaks the Ruby image test (AFAICT it breaks
anything that tries to use IPv6 to reach the internet). An ip6tables NAT rule is
added to handle this.
We could make these changes as part of scripts/, but these would overwrite
global values and possibly break users' systems.

This upgrades the Kokoro images, bazel toolchains used by RBE runners, and
rules_go, gazelle, and go toolchain versions.

This change moves all Docker images to a standard location, and abstracts the
build process so that they can be maintained in an automated fashion. This also
allows the images to be architecture-independent.
All images will now be referred to by the test framework via the canonical
`gvisor.dev/images/<name>`, where `<name>` is a function of the path within the
source tree.
In a subsequent change, continuous integration will be added so that the images
will always be correct and available locally.
In the end, using `bazel` for Docker containers is simply not possible. Given
that we already have the need to use `make` with the base container (for
Docker), we extend this approach to get more flexibility.
This change also adds a self-documenting and powerful Makefile that is intended
to replace the collection of scripts in scripts. Canonical (self-documenting)
targets can be added here for targets that understand which images need to be
loaded and/or built.

This change renames the tools/images directory to tools/vm for clarity, and
adds a functional vm_test. Sharding is also added to the same test, and some
documentation added around key flags & variables to describe how they work.
Subsequent changes will add vm_tests for other cases, such as the runtime tests.
