`terraform_modules` does not exist

[sureshjoshi]

I saw in the docs we reference this target, which hasn't existed since 2.11/2.12 times. I'm not entirely sure why it was removed though/

#15035

pants/src/python/pants/backend/terraform/target_types.py

Line 57 in a92bc34

Use `terraform_modules` to generate `terraform_module` targets for less boilerplate.

@tdyas You referenced it being inconsistent with other targets, but it seems like it's (now) more consistent to have a singular, and then a plural target generator.

Thoughts? If it makes sense for this to come back?

I don't recall exactly. Reconstructing my reasoning, the "inconsistency" is probably that the existing target generators generally make the singular targets in the same directory as the target generator whereas terraform_modules made targets within a whole directory hierarchy. For example, with python_sources, users repeat python_sources in a BUILD file in each subdirectory where it needs to apply. So it probably makes sense to not reintroduce terraform_modules.
