aws_elasticache_parameter_group always dirty

[hashibot]

This issue was originally opened by @wr0ngway as hashicorp/terraform#5854. It was migrated here as part of the provider split. The original body of the issue is below.

---

If I set a single parameter in an aws_elasticache_parameter_group, it does get applied, but subsequently the group is always seen as dirty - i.e. the aws side has multiple params in the group (defaults), but the local side only has the one I set.

resource "aws_elasticache_parameter_group" "cache" {
  name = "cache"
  family = "memcached1.4"
  description = "cache param group"

  parameter {
    name = "max_item_size"
    value = "5242880"
  }
}

result of subsequent plan:
