In ArchiveBackupAsync I get an error if I don't create the partition temp folder first

[PTC-JoshuaMatthews]

I found this example useful as a way to setup code based backup and restore for my stateful service.

I did get an error when attempting to restore my backup that the file location did not exist. This was due to there being a temp folder, but not temp/partitionId folder on my local 5 node cluster's filesystem. Maybe that's a different issue.

Ultimately I added

Directory.CreateDirectory(this.PartitionTempDirectory);

at line 91 of /Inventory.Service/AzureBackupStore.cs to get things working smoothly.

Just making this available for anyone experiencing the same issue.
