Updates for the latest k8s and etcd

Update things for the latest and greatest

Can you show the diff for commandline options for each component (v1.4.5 to v1.7.5). Kubernetes changes the commandline flags quite frequently. At least the default properties should by in-sync with the version offered.

Just a heads up this entire thing is broken at the moment. I just wanted to open the PR to get some visibility on what I was working on. Feedback would be super welcome.

Now that I have things matching the upstream unit files a bit more and using the systemd_unit resource I'm going to look at the default options. I'm sure there's quite a few new ones and that will need to get updated to work with 1.7.5 w/o the need for a wrapper cookbook defining new properties.

@aespinosa This works on Ubuntu. Debian has some cgroups issues that are going to need some additional work, but were broken already.

So here's a highlight of the changes:

Use systemd_unit to manage the systemd unit files and sync the unit files with upstream a bit Add a new property for the file ulimit for each service Add a new property for specifying the version of each service so you don't have to set the whole artifact URL to use a new version Default to k8s 1.7.6 Install the dependent packages for kubelets Require the master property to be set so services will properly start Use the new etcd cookbook that uses etcd 3.X Resolve all Chef 14 deprecation warnings and cookstyle warnings Test on Ubuntu as add ubuntu as a supported platform in the metadata Remove the usage of the apt cookbook in testing Use chef-apt-docker instead of manually setting up the repo in testing Test with docker 17.06.1
