[Feature] TFLint Integration

[scarowar]

Summary

Integrate TFLint as an optional pre-plan check to perform static analysis and identify potential errors and best practice violations in Terraform configurations.

Problem to solve

Currently, the pre-plan check includes only terraform validate. By extending this to include TFLint, users can opt in to perform static analysis on their Terraform configurations. This will help catch issues early and ensure safer, cleaner, and more reliable deployments.
