Kubelet: Remove nsinit related code and bump up minimum docker apiversion

Docker has native exec support after 1.3.x. We never need this code now.

As for the apiversion, because Kubernetes supports 1.8.x - 1.10.x now, we should bump up the minimum docker apiversion.
@yujuhong I checked the [changes](https://github.com/docker/engine-api/blob/master/types/versions/v1p20/types.go), we are not relying on any of those changes. So #23506 should work with docker 1.8.x+

bc62096ad5 Clean up host networking plugin checks for docker manager 
We can save a docker inspect in podInfraContainerChanged() because
it's only used within the useHostNetwork() block.  We can also
consolidate some code in createPodInfraContainer() because if
the pod uses the host network, no network plugin will be involved.

Finally, in syncPodWithSyncResult() we can consolidate some
conditionals because both hairpin setup and getting the container
IP are only relevant when host networking is *not* being used.

More specifically, putting the dm.determineContainerIP() call
into the !useHostNetwork() block is OK since if no network plugin
was called to set the container up, it makes no sense to call
the network plugin to retrieve the IP address that it did not
handle.  The CNI plugin even calls back into the docker manager
to GetContainerIP() which grabs the IP from docker, which will
always be "" for host networked containers anyway.

ae2f6a833a Reduce volume of logs generated at v(3) 
Node controller is generating a huge amount of logging at v(3) that is
more appropriate for v(5). Split the log into two levels and ensure it
also ends up on one line (so grep works).

The pod manager generates a v(4) pod output on sync that always contains
a newline - since the size of the pod is so excessive in output, kick it
to v(5) for deep debugging (we're pretty happy with this loop).

fff8a7c371 kubelet: Update engine version parsing to handle semantic versioning 
This updates the dockertools.dockerVersion to use a semantic versioning
library to more gracefully support engine versions which include
additional version fields.

Previously, go-dockerclient's APIVersion struct was use which only
handles plain numeric x.y.z version strings. With #19675, the library
was now used on the Docker engine string, however it is possible for the
engine string to include include additional information for beta, rc, or
distro specific builds.

This PR also enables the TestDockerRuntimeVersion test which was
previously just a FIXME and updates it to pass, and be used to test the
version string that cause #20005.

This negates the need for fsouza/go-dockerclient#451, since even with
that change, if a user was running Docker 1.10.0-rc1, this would cause
the kubelet to report it as simply 1.10.0.

a7b07c01df Update container runtime to properly report the engine and version 
This address a TODO when collecting the node version information so it
will properly report the configured runtime and its version. Previously,
this was hardcoded to "docker://" and the docker version, and would show
"docker://1.9.1" even when the kubelet was configured to use rkt.

With this change, it will use the runtime's Type() and Version() data.

This also changes the container.Runtime interface to add an APIVersion()
method. This can be used when the runtime has separate versions for the
engine and the API, such as with Docker. The Docker minimum version
validation has been updated to use APIVersion(), and
DockerManager.Version() now returns the engine version.
