Add TFLint configuration

[MaxymVlasov]

what

• That is a TFLint setup that we use in our repos.

why

• TFLint is able to detect many deprecations and violations, so better to use it whenever it possible

Note: It's the only configuration as is, not include fixes. I suggest doing next:

1. disable all rules
2. Enable rules one by one and fix all violations

Also, you may like to exclude: ^deprecated/ and add # tflint-ignore: <rule> # <description why it disabled> in some cases

Here are found violations (pre-commit run -a):

Terraform validate with tflint...........................................Failed
- hook id: terraform_tflint
- exit code: 2

Command 'tflint --init' successfully done:
Plugin `aws` is already installed

Other violations are trimmed

[max-lobur]

This will overlap #694 (when done lol)

[goruha]

@MaxymVlasov, thanks for your contribution.
Your changes were ahead of the cloudposse code quality strategy.
Currently, we are running tf linting for all components with shared workflows on the org level.

I have to close the PR.

[MaxymVlasov]

@goruha is there a chance to implement these changes in shared org-level workflows?

[goruha]

@MaxymVlasov is that enough?
