Remove kubelet dependency on pidof
Issue #26093 identified pidof as one of the dependencies of kublet
which could be worked around. In this PR, we just look at /proc
to construct the list of pids we need for a specified process
instead of running "pidof" executable

Kubelet: Add container ports label.
Addresses https://github.com/kubernetes/kubernetes/pull/30049#discussion_r73983952.
Add container ports label, although we don't use it now, it will make it easier to switch to new runtime interface in the future.

[kubelet] Auto-discover node IP if neither cloud provider exists and IP is not explicitly specified
One example where the earlier implementation failed is when running kubelet on CoreOS (bare-metal), where the nameserver is set to `8.8.8.8`. kubelet tries to lookup the node name agains Google DNS, which obviously fails. The kubelet won't recover after that.
The workaround hsa been to set `--hostname-override` to an IP address, but it's quite annoying to try to make a multi-distro way of getting the IP in bash for example. This way is much cleaner.
Refactored the function a little bit at the same time

Verify volume.GetPath() never returns ""
Add a new helper method volume.GetPath(Mounter) instead of calling
the GetPath() of the Mounter directly. Check if GetPath() is returning
a "" and convert that into an error.
Fixes#23163

information about the type of the Mounter, so let's log that if
there is a problem
