When we upgrade a node, we kill off all pods before performing a fresh
install. The issue with this is that we run the risk of killing the CNI
pod before we finish killing all other pods, leaving the CRI unable to
teardown the pod's networking. This works around that by first killing
any pods running without host networking so that the CNI can do its'
job, and then removing the remaining pods.

This removes the github.com/pkg/errors package in favor of the official
error wrapping in go 1.13.

This is preparation for implementing CRI runner.
CRI client moved into its own package, I split it into multiple files
and added rudimentary tests for it.
