CDK - Explore CDK TableV2 / GlobalTable

[huntharo]

Motivations

• The DynamoDB Table needs to be replicated to several origins for the OriginRequest handler to do quick lookups
• CDK added TableV2 that wraps GlobalTable

Acceptance Criteria

• Allow a TableV2 to be passed in to the constructs
• Add a config parameter for the OriginRequest handler to list the regions that have tables
• Add parameters to the CDK constructs to specify which regions have the table
