• terraform init: Displays a warning when deprecated modules are in use.

Description

All module deprecation info is consolidated into and displayed as a single warning upon running terraform init. This includes both cases of where the module does, or does not, need installation. Furthermore, the warning can be raised for both modules that are directly used in configuration, as well as any external dependencies they depend on.
