feat: add support dynamoDB batch tasks using AWS SDK service integration

[tvhees]

Creates the IAM Role for tasks which use the batch tasks targeting one or more dynamoDB tables. Supports BatchWriteItem and BatchGetItem

Currently a task defined this way will result in the following error.

Cannot generate IAM policy statement for Task state

With this change it correctly deploys and runs with permissions created for the minimal set of tables if possible.

RequestItems may specify the table names as keys, in which case permission resources will be applied only to the tables listed e.g.

WriteBatchToDynamo:
    Type: Task
    Resource: arn:aws:states:::aws-sdk:dynamodb:batchWriteItem
    Parameters:
      RequestItems:
        usersTable: $.userRequests
        postsTable: $.postRequests
      ReturnConsumedCapacity: TOTAL
    ResultPath: $.writeResult
    End: true

RequestItems can also be specified fully at runtime. In this case a '*' resource is necessary.

WriteBatchToDynamo:
    Type: Task
    Resource: arn:aws:states:::aws-sdk:dynamodb:batchWriteItem
    Parameters:
      RequestItems.$: $.requestItems
      ReturnConsumedCapacity: TOTAL
    ResultPath: $.writeResult
    End: true
