Dep Support

This patch fixes issue #91 by adding support for the official Go
dependency tool, Dep. The solution is a nearly-empty Go source file at
"lib/go/csi.go" that defines a package with no functional code. However,
this package will enable the ability to nil-import
"github.com/container-storage-interface/spec/lib/go" so that the Dep
tool discovers a valid Go package (a directory with one or more Go
sources in it).

For information on why the resolution is not to simply import
"github.com/container-storage-interface/spec/lib/go/csi" please see
issue #91.
