When the buffer isn't filled to capacity a new slice is created that's
smaller than the original. In that case the smaller slice is returned to
the pool which prevents the rest of the capacity from being used again.

The solution is to pass the original slice through and attach the
length. This allows the original slice to be returned to the pool once
the operation is complete.

This change also simplifies the `sendChunk` method, ensuring that the
buffer is returned to the TransferManager even when no bytes were read
from the reader.

This function only takes an io.Reader in azure-storage-blob-go,
& wal-g abstracts over multiple upload mechanisms which all operate on io.Reader

Updating sb to handle breaking changes in azcore

At the moment we're not using azcore's HTTP library, so we don't need to test for specific errors that come from azcore.
