Research direction

Start at the Aws::DynamoDB::Client#wait_until entry point and reproduce the table_not_exists case from the issue. Trace how ResourceNotFoundException is handled for a missing table, then verify that the waiter returns nil without showing a client error.

Description

feature-request
Describe the bug

When I call Aws::DynamoDB::Client.new.wait_until(:table_not_exists, table_name: 'this_does_not_exist')

then I see a client error

[Aws::DynamoDB::Client 400 0.004513 0 retries] describe_table(table_name:"this_does_not_exist") Aws::DynamoDB::Errors::ResourceNotFoundException Cannot do operations on a non-existent table

IMHO this is unexpected behavior. When I tell the client to wait until a table does not exist (e.g. after a delete call) and it doesnt exist, it should just silently proceed.
