[ep-infra] Run the postUpgradeTask from inside Terraform modules
Context
The postUpgradeTask defined in !792 (merged) does not seem to work, and it seems to be because we don't run the terraform providers lock
from inside Terraform modules.
What's in this MR?
We run the terraform providers lock
from inside each modules after an update on the Terraform lock files of any module.
