Add ability to disable validation step for s3 backend `kms_key_id`

[PeppaTheC]

Terraform Version

1.7.3

Use Cases

Hi, we have our own s3 like storage to save terraform state.

  backend "s3" {
    endpoints = {
      s3 = "https://private.storage.net"
    }
    bucket   = "<BUCKET>"
    region   = "ua-central1"
    key      = "terraform.tfstate"

    skip_s3_checksum            = true
    skip_region_validation      = true
    skip_requesting_account_id  = true
    skip_credentials_validation = true

    encrypt = true
    access_key = "<KEY>"
    secret_key = "<SECRET>"
    kms_key_id = "<KEY_ID>"
  }

Starting from terraform version 1.6.0 there is a validation step for kms_key_id field, here.

And so, we have error

2024-02-19T18:36:52.200+0300 [INFO]  Terraform version: 1.7.3

| Error: Invalid KMS Key ID
| 
|   on provider.tf line 29, in terraform:
|   29:     kms_key_id = "****"
| 
| Value must be a valid KMS Key ID, got "****"

Attempted Solutions

There is no existing solution.

Proposal

Can we add new flag/parameter to s3 backend configuration to disable kms_key_id validation?

Hi! Any updates?

| Value must be a valid KMS Key ID, got "" For clarity, I'm adding the example of KMS Key ID: "abjl6mft1vop****"

In versions under 1.6.0 we had an ability to use alternative S3-like backends (for example Yandex Storage) and alternative KMS-like services (Yandex KMS)

But now it is impossible to use new versions of terraform with yandex provider in such scenarios according to this issue
