Request to support premium storage account. This would allow much higher scaling of number of vm's and increased performance of the agents stood up on the storage account.

Currently when trying to use premium storage account logs indicate that 'Block Blobs are not supported'. I believe this is because the customscriptextension is a block blob and is trying to save to premium storage and is unsupported. Perhaps there could be a separate storage account field for the script extension location and this storage account would be required to be standard storage in order to support block blobs.
