[Storage] Add samples for the new features in Track 2

[HarshaNalluru]

Example - Batch

[mrsufgi]

for SAS generation I followed the test spec files for a "how to", I also dug in a little deeper and found:

const userDeletgationKey = await blobServiceClient.getUserDelegationKey(startTime, expiryTime);

@jiacfan's comment -
Would we provide example/sample for BlobSASSignatureValues? I think that would be helpful.

From #4680

There are no samples showing the usage of "@azure/abort-controller".
This issue is to track to add some in storage packages.

Relevant work from #5788

Add more samples for general use cases

• example downloading - download() vs downloadToFile()
• for SAS credential generation

Clients in samples have too many layers - create a blobServiceClient, blobServiceClient.getContainerClient()

• Add samples for new ContainerClient()
