Check in the vendor directory

Travis seems to be having issues pulling deps, so we'll have to check in
the vendor directory and prevent the makefile from trying to regenerate
it normally.

vendor/k8s.io/apimachinery/pkg/conversion/doc.go

+// Package conversion provides go object versioning.
+//
+// Specifically, conversion provides a way for you to define multiple versions
+// of the same object. You may write functions which implement conversion logic,
+// but for the fields which did not change, copying is automated. This makes it
+// easy to modify the structures you use in memory without affecting the format
+// you store on disk or respond to in your external API calls.
