Avoid fetching `SnapshotService` from client every time. Fetch it once
and then store when creating the image service.
This also allows to pass custom snapshotter implementation for unit
testing.

Use `image.Store` and `content.Store` stored in the ImageService struct
instead of fetching it every time from containerd client.

Both containerd and graphdriver image service use the same code to
create the cache - they only supply their own `cacheAdaptor` struct.
Extract the shared code to `cache.New`.

Move image store backend specific code out of the cache code and move it
to a separate interface to allow using the same cache code with
containerd image store.

Rather than error out if the host's resolv.conf has a bad ndots option,
just ignore it. Still validate ndots supplied via '--dns-option' and
treat failure as an error.

When this was called concurrently from the moby image
exporter there could be a data race where a layer was
written to the refs map when it was already there.
In that case the reference count got mixed up and on
release only one of these layers was actually released.

When IPv6 is disabled in a container by, for example, using the --sysctl
option - an IPv6 address/gateway is still allocated. Don't attempt to
apply that config because doing so enables IPv6 on the interface.

When configuring the internal DNS resolver - rather than keep IPv6
nameservers read from the host's resolv.conf in the container's
resolv.conf, treat them like IPv4 addresses and use them as upstream
resolvers.
For IPv6 nameservers, if there's a zone identifier in the address or
the container itself doesn't have IPv6 support, mark the upstream
addresses for use in the host's network namespace.

RootlessKit will print hints if something is still unsatisfied.

In de2447c, the creation of the 'lower' file was changed from using
os.Create to using ioutils.AtomicWriteFile, which ignores the system's
umask. This means that even though the requested permission in the
source code was always 0666, it was 0644 on systems with default
umask of 0022 prior to de2447c, so the move to AtomicFile potentially
increased the file's permissions.
This is not a security issue because the parent directory does not
allow writes into the file, but it can confuse security scanners on
Linux-based systems into giving false positives.

The field will still be present in the response, but will always be
`false`.
Searching for `is-automated=true` will yield no results, while
`is-automated=false` will effectively be a no-op.

In a container-create API request, HostConfig.NetworkMode (the identity
of the "main" network) may be a name, id or short-id.
The configuration for that network, including preferred IP address etc,
may be keyed on network name or id - it need not match the NetworkMode.
So, when migrating the old container-wide MAC address to the new
per-endpoint field - it is not safe to create a new EndpointSettings
entry unless there is no possibility that it will duplicate settings
intended for the same network (because one of the duplicates will be
discarded later, dropping the settings it contains).
This change introduces a new API restriction, if the deprecated container
wide field is used in the new API, and EndpointsConfig is provided for
any network, the NetworkMode and key under which the EndpointsConfig is
store must be the same - no mixing of ids and names.
