Adds tag support to the `aws_dynamodb_table` resource. Also adds a test for the resource, and a test to ensure that the tags are populated correctly from a resource import.

resource
We had a line on the Update func that said:
```
Hash key can only be specified at creation, you cannot modify it.
```
The resource has now been changed to ForceNew on the hashkey
```

aws_dynamodb_table.demo-user-table: Destroying...

```
This commit exports the `arn` as well as the `id`, since IAM
roles require the full resource name rather than just the table
name. I'd even be in favor or having `arn` as the `id` since the
<region, tablename> pair is the uniqueness constraint, but this
will keep backwards compatibility:
