support kinesis streams besides dynamodb streams for streaming from source

[tarzanek]

as per https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Streams.KCLAdapter.Walkthrough.html

we could leverage https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/java/example_code/dynamodb
and replay kinesis instead of DynamoDB stream

(we'd need a spark version of above though)

advantage is that kinesis stream can have 1 month old history and can replay from a timestamp

If the source is s3 export, we can use describe stream "start time" as timestamp to start the stream from the time the s3 export was created.

sample replayer from @nopzdk https://github.com/nopzdk/kinesis-to-alternator/tree/main

[tarzanek]

we will need similar kinesis stream support for CQL too - #251
so redesign of properly handling this feature might be needed (to be pluggable similar like we have for read/write RDDs)

[nopzdk]

If dynamoDB stream already is enabled we should use the stream instead of failing after initial transfer.
we should be able to choose between Kinesis or dynamodb stream, in case both are enabled on the table,
when using kinesis stream we need to supply AT_TIMESTAMP, this can be either the time the migration started if source is DynamoDB or the starttime of the s3 export .
