5.3

Updated RDS module to use resource "random_password", instead of resource "random_string" to generate the db password.
This will fix pipeline exposing the db password.

Also reverted dynamic "parameter" changes which were in the master branch, but have never been part of an official release.

resource "aws_db_parameter_group" "custom_parameters" {
  name = local.identifier
  family = var.rds_family
  dynamic "parameter" {
    for_each = var.db_parameter
    content {
      apply_method = lookup(parameter.value, "apply_method", null)
      name = parameter.value.name
      value = parameter.value.value
    }
  }
}
