.travis, build: autodelete old unstable archives (#13867)

Browse Source 
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).

# Azure Storage SDK for Go
The `github.com/Azure/azure-sdk-for-go/storage` package is used to perform operations in Azure Storage Service. To manage your storage accounts (Azure Resource Manager / ARM), use the [github.com/Azure/azure-sdk-for-go/arm/storage](../arm/storage) package. For your classic storage accounts (Azure Service Management / ASM), use [github.com/Azure/azure-sdk-for-go/management/storageservice](../management/storageservice) package.
This package includes support for [Azure Storage Emulator](https://azure.microsoft.com/documentation/articles/storage-use-emulator/)
