[Enhancement]: `r/aws_redshift_cluster`: Support managed master passwords

[jar-b]

Description

The Redshift [Create|Modify]Cluster API's include a ManageMasterPassword argument, which is not implemented in the corresponding Terraform resource. Support should be added similar to the implementation for aws_db_instance.

ManageMasterPassword
If true, Amazon Redshift uses AWS Secrets Manager to manage this cluster's admin credentials. You can't use MasterUserPassword if ManageMasterPassword is true. If ManageMasterPassword is false or not set, Amazon Redshift uses MasterUserPassword for the admin user account's password.

Type: Boolean

Required: No

Affected Resource(s) and/or Data Source(s)

• aws_redshift_cluster

Potential Terraform Configuration

resource "aws_redshift_cluster" "example" {
  cluster_identifier = "tf-redshift-cluster"
  database_name      = "mydb"
  master_username    = "exampleuser"
  node_type          = "dc1.large"
  cluster_type       = "single-node"

  manage_master_password = true
}
