### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

DynamoDB does not correctly namespace resources based on region and account ID. 

For instance, using the same table name across accounts and regions throws an error.

### Expected Behavior

It must be possible to create resources with same name on different regions and/or different accounts.

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

#### Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)

```
  $ AWS_ACCESS_KEY_ID=445500880268 AWS_DEFAULT_REGION=eu-central-1 \
    awslocal dynamodb create-table --table-name CertificateTargets-local1 \
        --key-schema AttributeName=target_uuid,KeyType=HASH \
        --attribute-definitions AttributeName=target_uuid,AttributeType=S \
        --provisioned-throughput ReadCapacityUnits=1000,WriteCapacityUnits=1000

  $ AWS_ACCESS_KEY_ID=445500880268 AWS_DEFAULT_REGION=us-east-1 \
    awslocal dynamodb create-table --table-name CertificateTargets-local1 \
        --key-schema AttributeName=target_uuid,KeyType=HASH \
        --attribute-definitions AttributeName=target_uuid,AttributeType=S \
        --provisioned-throughput ReadCapacityUnits=1000,WriteCapacityUnits=1000

    # ResourceInUseException!

  $ AWS_ACCESS_KEY_ID=000000000000 \
    awslocal dynamodb create-table --table-name CertificateTargets-local1 \
        --key-schema AttributeName=target_uuid,KeyType=HASH \
        --attribute-definitions AttributeName=target_uuid,AttributeType=S \
        --provisioned-throughput ReadCapacityUnits=1000,WriteCapacityUnits=1000

    # ResourceInUseException!
```
