This commit adds a build step to travis to auto-delete unstable archives older than 14 days (our regular release schedule) from Azure via ci.go purge. The commit also pulls in the latest Azure storage code, also switching over from the old import path (github.com/Azure/azure-sdk-for-go) to the new split one (github.com/Azure/azure-storage-go).
