• Adds input to limit the chunk upload size, useful for self-hosted runners with slower upload speeds
• No-op when executing on GHES

• Update @actions/cache package to v1.0.2 which allows cache action to use posix format when taring files.

• Replaces the http-client with the Azure Storage SDK for NodeJS when downloading cache content from Azure. This should help improve download performance and reliability as the SDK downloads files in 4 MB chunks, which can be parallelized and retried independently
• Display download progress and speed
