7561a0f96e memory manager: provide new flag var to parse reserved-memory parameter 
The new flag will parse the `--reserved-memory` flag straight forward
to the []kubeletconfig.MemoryReservation variable instead of parsing
it to the middle map representation.

It gives us possibility to get rid of a lot of unneeded code and use the single
presentation for the reserved-memory.

75242fce7a kubelet: allow specifying dual-stack node IPs on bare metal 
Discussion is ongoing about how to best handle dual-stack with clouds
and autodetected IPs, but there is at least agreement that people on
bare metal ought to be able to specify two explicit IPs on dual-stack
hosts, so allow that.

Remove all uses of dockershim from cmd/kubelet 
We can remove all uses of `dockershim` from `cmd/kubelet`, by just
passing the docker options to the kubelet in their pure form, instead of
using them to create a `dockerClientConfig` (which is defined in
dockershim). We can then construct the `dockerClientConfig` only when we
actually need it.

Remove ExperimentalDockershim from kubelet 
Remove one of two uses of Dockershim in `cmd/kubelet`. The other is for
creating a docker client which we pass to the Kubelet... we will handle
that refactor in a separate diff.

I'm fairly confident, though need to double check, that no one is
actually using this experimental dockershim behavior. If they are, I
think we will want to find a new way to support it (that doesn't require
using the Kubelet only to launch Dockershim).

Remove pkg/util/mount (moved out of tree) 
This patch removes pkg/util/mount completely, and replaces it with the
mount package now located at k8s.io/utils/mount. The code found at
k8s.io/utils/mount was moved there from pkg/util/mount, so the code is
identical, just no longer in-tree to k/k.

Fix dynamic kubelet config init order

All callers are changed to use the `*NewHostUtil*` methods instead of
directly instantiating the concrete types.

be7da5052f Refactor pkg/util/mount to be more reusable 
This patch refactors pkg/util/mount to be more usable outside of
Kubernetes. This is done by refactoring mount.Interface to only contain
methods that are not K8s specific. Methods that are not relevant to
basic mount activities but still have OS-specific implementations are
now found in a mount.HostUtils interface.

1c045a09db Move nsenter mounter to pkg/volume/util/nsenter 
As part of moving pkg/util/mount out of tree, the NSEnter implementation
of mount.Interface needs to be relocated out of pkg/util/mount, as it is
K8s specific. This patch relocates that mounter implementation to
pkg/volume/util/nsenter.

Since the NSEnter mounter shares a lot of its logic with the Linux
mounter implementation, many of the previously private methods of the
Linux mounter are now made public to maintain that shared code.

Additionaly, it was observed that *all* mount.Interface implemenations
were using the same common method for IsNotMountPoint, so this patch
removes that method from the mount.Interface definition and just exports
the common implementation instead.
