[SDK-Bindings - Tables] Implement converter in Tables worker extension to support TableClient +

[liliankasem]

Problem Statement

Implement TablesConverter to enable binding to the TableClient, TableEntity and IEnumerable<TableEntity> types so that we have parity with in-proc.

• Tables worker extension project

Tasks

• Implement converter that enables binding to a single TableClient, TableEntity and multiple TableEntity's
  • Being able to bind to multiple table entities looks like this: IEnumerable<TableEntity>, IAsyncCollector<TableEntity>*
• Implement managed identity support via Options and AzureComponentFactory
• Write unit tests for converter
• Write unit tests for any other classes implemented (such as the config and options classes)
• Write E2E tests for:
  • Function with Tables input binding to TableClient
  • Function with Tables input binding to TableEntity
  • Function with Tables input binding to IEnumerable<TableEntity>

• We may not need to support IAsyncCollector<TableEntity> so start with all of the other types first and we can come back to this at the end

Definition of Done

1. Worker Tables extension package is released (as a preview package) with support for binding to a TableClient, TableEntity, and IEnumerable<TableEntity>
2. Unit & E2E tests written and checked-in
3. Microsoft documentation updated to detail support for the new SDK-bindings

First, utilize the author guide to implement this changes:

• Dotnet extension author guide

If you're stuck, use the Cosmos DB and Blob extensions as examples of how to do this; they both have converters implemented with managed identity support:

• Blob worker extension
• [Cosmos worker extension(https://github.com/Azure/azure-functions-dotnet-worker/tree/feature/sdk-type-binding/extensions/Worker.Extensions.CosmosDB/src)
