Option to skip local value (for terraform_unused_declarations)

[rhiser]

Is there an ability to specify which unused terraform_unused_declarations can be set.

I would like the ability to define say local {foo = "bar"}, and not have tflint complain that this local is being not used. Due to some complex conditionals that are being used for a handful of similar repos I have, I would like to be able to create locals even though they may not be used.

I know I can disable this ruleset, but like it's use case for variables and data sources (just don't want it for locals due to my unique case and module usage)

Rule configuration is kept intentionally minimal.

You can use tflint-ignore annotations to handle this, which ultimately provides a better developer experience for most use cases since the configuration is kept close to the code.

There's a proposal to have these annotations also work at the block level: terraform-linters/tflint#1641. In which case you'd be able to ignore violations across all locals in a given block. Whereas currently you'd have to include it on each unused local value expression. For generic boilerplate a file-level annotation might be suitable too.

I don't anticipate adding a rule config attribute for which block types to check such that you could ignore all unused locals in all blocks. I'd rather invest that time in making ignores more flexible versus implementing granular opt-outs in specific rules.
