Strip comments from configure-vm.sh for gce

We are getting very close to the 32KiB limit on GCE metadata entry length. We used to strip comments before putting the value in metadata, but I think we removed it in a refactor because it wasn't absolutely necessary, and leaving it out made the scripts slightly cleaner. It's close to being necessary again.

Removing comments reduces the size from 31,609B to 27,221B: https://www.diffchecker.com/0xmmecvw.
