Added component to initialize AWS DynamoDB client.

Component initialization

(component/system-map
   :dynamo-db (tc.ddb.component/map->AwsDynamoDb {:credentials (when-not (= profile :prod)
                                                       create-dev-credentials)
                                        :endpoint (when-not (= profile :prod)
                                                    (URI. development-url))
                                        :region Region/AP_NORTHEAST_1}))

Getting item from DynamoDB table

(let [partition-key {:name "email" :value "sample@example.com"}]
  (tc.ddb.protocol/get-item dynamo-db-component
                            "example-table"
                            partition-key))

The code above will return data like {:name "Tarou" :age 20 :is-student true}.

Limitations

Only string, int, bool is supported at the moment.
