Update dependencies and the test images to use pause 3.5. We also
provide a changelog entry for the new container image version.

- libcontainer renamed
`github.com/opencontainers/runc/libcontainer/configs` to
`github.com/opencontainers/runc/libcontainer/devices` so use the new
references
- Update `dockershim` `ContainerCreate` call after docker update to
v20.10.2
the hostport manager was not taking into consideration the hostIP
when binding the socket of the hostPort, causing that the same
HostPort can not be used with different IP addresses.
We can set the container cpuset.cpus diring the creation and it
will not need to call to update resources after the container creation.
Additional side effect of the change, that the runc process that responsible
to create the container will run with the same CPU affinity because the
runc runs on the cpuset provided in the config.json arg.
It will allow to prevent undesirable interupts on isolated CPUs.

This change also involves adding a custom error type for probe timeouts
so that the kubelet exec prober can distinguish between failed probes
that have exited or probes that have timed out.

the third phase of dual stack is a very complex change in the API,
basically it introduces Dual Stack services. Main changes are:
- It pluralizes the Service IPFamily field to IPFamilies,
and removes the singular field.
- It introduces a new field IPFamilyPolicyType that can take
3 values to express the "dual-stack(mad)ness" of the cluster:
SingleStack, PreferDualStack and RequireDualStack
- It pluralizes ClusterIP to ClusterIPs.
The goal is to add coverage to the services API operations,
taking into account the 6 different modes a cluster can have:
- single stack: IP4 or IPv6 (as of today)
- dual stack: IPv4 only, IPv6 only, IPv4 - IPv6, IPv6 - IPv4
* [FIX] add integration tests for dualstack
* generated data
* generated files

When trying to fix a dockershim issue, there were not any unit tests
for dockershim/exec.go and it was difficult to add the corresponding
unit test for the bug.
This adds the unit tests for avoiding such situation in the future.
