 *  3) Pass the records to #deleteAllElements which in turn sends a delete request for each
 *  of them
 *  4) Return a list of promises using Promise.all() to the caller
 *
 * @param tableName the table we want to purge
 * @param ddbApi the AWS dynamodb service that holds the connection
 * @returns concatenation of all delete request promises
