Recreating the Redis cluster does not work

[fbergero]

What is the current behavior? Currently the module tries to create the replication group before destroying any previous existing one.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.

• Create a cluster
• Change any parameter that requires re-creating (Encryption enabled for example)
• Re apply
• The API to create the new version of the cluster will fail since there is already a replication group with than name.

What is the expected behavior? The module should remove the existing cluster first and then create the replacement. This should be removed https://github.com/umotif-public/terraform-aws-elasticache-redis/blob/main/main.tf#L82
