FP-friendly modular AWS SDK for JavaScript

[trivikr]

Creating this discussion from GitHub Issue #1557
Thanks to @thuringia for the suggestion.

In JS SDK v3, the command objects are passed to .send() operations as follows:

import { DynamoDBClient, ListTablesCommand } from "@aws-sdk/client-dynamodb";

const client = new DynamoDBClient(clientParams);
await client.send(new ListTablesCommand(commandParams));

And FP-friendly version would help to curry SDK-functions for example:

import { dynamoDB, listTables } from "@aws-sdk/client-dynamodb";

const client = dynamoDB({});
await listTables(client, commandParams);

The paginators are already FP-friendly as follows:

import { DynamoDBClient, paginateListTables } from "@aws-sdk/client-dynamodb";

const client = new DynamoDBClient({}); 

const tableNames = [];
for await (const page of paginateListTables({ client }, {})) {
    // page contains a single paginated output.
    tableNames.push(...page.TableNames);
}

The waiters (implementation in-progress) are also going to be similar.

import { DynamoDBClient, waitForTableExists } from "@aws-sdk/client-dynamodb";

const client = new DynamoDBClient({}); 
await waitForTableExists({ client }, { TableName });
