Add Azure Blob support using azure-storage-blob-nio

[droazen]

Let's see if we can get Azure Blob support working in GATK using the existing azure-storage-blob-nio NIO plugin:

https://search.maven.org/artifact/com.azure/azure-storage-blob-nio/12.0.0-beta.8/jar

Currently auth info needs to be manually passed in, unlike with the Google NIO plugin, but I've opened a feature request to get the auth info automatically from the environment:
