During the official build transition, use sandboxes for:
1. Blog container for the artifacts and checksums
2. MyGet feed
3. VS NuGet feed
4. Versions repo
In addition, skip publishing packages to the apt-get repo, because a
sandbox is not trivial to configure.
Currently, using a custom container name is supported for only some
publish steps. This commit makes it supported for all publish steps.
This commit also ensures that the Overwrite property is specified on all
calls to the UploadToAzure task.
