feat: Cross-account DNS and ACM resource creation

[dannyibishev]

Description

The proposed changes will allow both cross-account and single account ACM creation with DNS validation.

Motivation and Context

I needed to create my ACM certificates in account B but my hosted zone belongs to Account A. These changes allowed me to meet this requirement.

Breaking Changes

I believe the two providers will now always be required and need to be explicitly passed down.

In the module call, people will now need to pass the providers block with the two required providers.

  providers = {
    aws.acm = aws.account_b,
    aws.dns = aws.account_a
  }

or if they use a single account then the following block should still work

  providers = {
    aws.acm = aws,
    aws.dns = aws
  }

How Has This Been Tested?

I have tested by calling the fork with my branch

module "acm" {
  source = "[email protected]:Pod-Point/terraform-aws-acm.git?ref=patch-cross-account-provider"

  providers = {
    aws.acm = aws.<ommited>,
    aws.dns = aws.<ommited>
  }

  domain_name = var.project_domain
  zone_id     = var.pod_point_hosted_zone_id

  subject_alternative_names = var.additional_aliased_domains

  wait_for_validation                = true
  validation_allow_overwrite_records = false
}

Any chance this can be looked at

Would be great to see this one merged! How does it handle the case of using single account? Does the user still need to path 2 providers even if it's the same one?

Thanks for the feature! Already updated our code - works like a charm. No need to create validation records manually anymore.

Thank you for the confirmation, @mputilin !
