integrationtest: include dynblock usage in the "terraformlike" test

Browse Source 
Terraform is the prime use-case for the dynblock extension, so we'll
include this here currently as a proof-of-concept for Terraform's usage,
but eventually (once Terraform is actually using it) this'll give some
insurance that it doesn't get broken.
