Instead of having to go through files or registry values as is currently the
case.
While adding GMSA support to Kubernetes (https://github.com/kubernetes/kubernetes/pull/73726)
I stumbled upon the fact that Docker currently only allows passing Windows
credential specs through files or registry values, forcing the Kubelet
to perform a rather awkward dance of writing-then-deleting to either the
disk or the registry to be able to create a Windows container with cred
specs.
This patch solves this problem by making it possible to directly pass
whole base64-encoded cred specs to the engine's API. I took the opportunity
to slightly refactor the method responsible for Windows cred spec as it
seemed hard to read to me.
Added some unit tests on Windows credential specs handling, as there were
previously none.
Added/amended the relevant integration tests.
I have also tested it manually: given a Windows container using a cred spec
that you would normally start with e.g.
```powershell
docker run --rm --security-opt "credentialspec=file://win.json" mcr.microsoft.com/windows/servercore:ltsc2019 nltest /parentdomain
# output:
# my.ad.domain.com. (1)
# The command completed successfully
```
can now equivalently be started with
```powershell
$rawCredSpec = & cat 'C:\ProgramData\docker\credentialspecs\win.json'
$escaped = $rawCredSpec.Replace('"', '\"')
docker run --rm --security-opt "credentialspec=raw://$escaped" mcr.microsoft.com/windows/servercore:ltsc2019 nltest /parentdomain
# same output!
```
I'll do another PR on Swarmkit after this is merged to allow services to use
the same option.
(It's worth noting that @dperny faced the same problem adding GMSA support
to Swarmkit, to which he came up with an interesting solution - see
https://github.com/moby/moby/pull/38632 - but alas these tricks are not
available to the Kubelet.)

It is wrong to pass an arbitrary string to a function expecting
%-style formatting. One solution would be to replace any % with %%,
but it's easier to just do what this patch does.

Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.

It does not make any sense to vary this based on whether the
rootfs is read only. We removed all the other mount dependencies
on read-only eg see #35344.

I noticed this test failed on Windows:
> 17:46:24 docker_cli_run_test.go:4361:
> 17:46:24 c.Fatal("running container timed out") // cleanup in teardown
I also noticed that in general tests are running slower on Windows,
for example TestStartAttachSilent (which runs a container with
`busybox echo test` and then starts it again) took 29.763s.
This means a simple container start can easily take 15s, which
explains the above failure.
Double the timeout from 15s to 30s.

Update and unify the `busybox` images on all arches to the `glibc` multi-arch
version and remove the temp workaround on amd64 which uses the old version
busybox (v1.26) before this PR to bypass the failure of those network related
test cases. Also, this PR will fix all the network related issues with `glibc`
version `busybox` image.

/dev is mounted on a tmpfs inside of a container. Processes inside of containers
some times need to create devices nodes, or to setup a socket that listens on /dev/log
Allowing these containers to run with the --readonly flag makes sense. Making a tmpfs
readonly does not add any security to the container, since there is plenty of places
where the container can write tmpfs content.
I have no idea why /dev was excluded.

If the user specifies a mountpath from the host, we should not be
attempting to chown files outside the daemon's metadata directory
(represented by `daemon.repository` at init time).
This forces users who want to use user namespaces to handle the
ownership needs of any external files mounted as network files
(/etc/resolv.conf, /etc/hosts, /etc/hostname) separately from the
daemon. In all other volume/bind mount situations we have taken this
same line--we don't chown host file content.

Current insider builds of Windows have support for mounting individual
named pipe servers from the host to the guest. This allows, for example,
exposing the docker engine's named pipe to a container.
This change allows the user to request such a mount via the normal bind
mount syntax in the CLI:
docker run -v \\.\pipe\docker_engine:\\.\pipe\docker_engine <args>
