Assigning to @ace-n as it's in functions.

[ace-n]

I think @stew-r (GCF PM) had some objections to killing off our Node 6 samples. (Personally I don't mind, but we're not deprecating disabling the Node 6 runtime until 2020.)

[stew-r]

Let's not delete samples specific to Cloud Functions until we decommission the runtime.
