Update to Terraform v1.0.11
Update to Terraform v1.0.11

It turns out I'd accidentally been using the new version for the past few days. Did a bunch of terraform applies, and nothing exploded. So I think we're safe to make the update.

0.14 -> 0.15 -> 1.0 wasn't very exciting in any case. No major breaking changes that we'd have expected to impact us
