Fix kubernetes version #

[celskeggs]

Running "kubectl version" gives us the following:

Client Version: version.Info{Major:"", Minor:"", GitVersion:"v0.0.0-master+$Format:%h$", GitCommit:"$Format:%H$", GitTreeState:"", BuildDate:"1970-01-01T00:00:00Z", GoVersion:"go1.12.10", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"{gitMajor}", Minor:"{gitMinor}", GitVersion:"{gitVersion}", GitCommit:"{gitCommit}", GitTreeState:"{gitTreeState}", BuildDate:"{buildDate}", GoVersion:"go1.12.10", Compiler:"gc", Platform:"linux/amd64"}

We should fix this to give us something more reasonable. See #105 for the last time this happened.

Given that this is a regression, we should set up a test to confirm this continues to work in the future.

This is blocking #29, because Rook requires correct version reporting to function. This is now much higher-priority!
