requestTimeout should be added back in Azure BlobClient package

[plameniv]

The requestTimeout parameter of the IBlobStorageConfiguration has been removed. It used to be passed to the createBlockBlobFromText of the BlobService from the azure-storage package.

This parameter is no longer used during the blob creation coming from package @azure/storage-blob however it can be passed in the constructor for BlobServiceClient as part of StoragePipelineOptions

constructor(url: string, credential?: StorageSharedKeyCredential | AnonymousCredential | TokenCredential, options?: StoragePipelineOptions);

StoragePipelineOptions has a field retryOptions of type StorageRetryOptions which has the tryTimeoutInMs field.

We can add the timeout back in.
