Implement Pulling Patch Data from Azure Data Blob Instead of Web Server

[Kokotewa]

It is desirable to expand patcher functionality to be able to source data assets from an azure data blob. This is desirable for these reasons:

• reduces bandwidth requirements/congestion on primary web server
• azure data blob is more suited to large / rapid file transfer than a web server

Unfortunately, due to the relative infancy of the Rust:Azure SDK, it would be recommended to postpone work in this area until the SDK becomes more stable to avoid future re-work.

Hi,
Indeed, it would be great to support more file storage options for serving patches.
I would definitely wait until a proper v0.1 is released before integrating that crate.

Feel free to assign it to me. I'll sit on it for now and begin work when the crate becomes a more mature.
