@z0rc, thanks for your contribution!
Currently, tests are failing:

 Error:      	Received unexpected error:
      FatalError{Underlying: error while running command: exit status 1; ╷
      │ Error: Unsupported argument
      │ 
      │   on ../../main.tf line 66, in resource "aws_eks_cluster" "default":
      │   66:   zonal_shift_config            = var.zonal_shift_config
      │ 
      │ An argument named "zonal_shift_config" is not expected here. Did you mean

      ╵}

could you please update zonal_shift_config to use a block? see access_config as an example.

[z0rc]

@gberenice I decided to use dynamic block here, as it optional in provider and most configurations won't have it set.

Okay, almost there. Need a bit more time.

@gberenice ready to test.
