/**
* Upload the given file to an Azure Storage container as a block blob.
*
* Block blobs are comprised of blocks, each of which is identified by a block ID.
* This allows creation or modification of a block blob by writing a set of blocks
* and committing them by their block IDs, resulting in an overall efficient upload.
*
* If writing a block blob that is no more than 64MB in size, upload it
* in its entirety with a single write operation. Otherwise, chunk the blob into discrete
* blocks and upload each of them, then commit the blob ID to signal to Azure that they
* should be combined into a blob. Files over 64MB are then deleted from temporary local storage.
*
* When you upload a block to a blob in your storage account, it is associated with the
* specified block blob, but it does not become part of the blob until you commit a list
* of blocks that includes the new block's ID.
*
* @param string $containerName The container to add the blob to.
* @param string $blobName The name of the blob to upload.
* @param string $localFileName The full path to local file to be uploaded.
* @param string $blobContentType Optional. Content type of the blob.
* @param array $metadata Optional. Metadata to describe the blob.
*
* @throws \Exception|ServiceException Exception if local file can't be read;
* ServiceException if response code is incorrect.
