Partially uploaded packages persist on the Octopus Server

[tothegills]

When a package is being uploaded it is saved in the users temp folder. If the upload is interrupted, the temporary file persists in the temp folder.

To reproduce (I used a 6GB package):

• Run the Octopus Server as administrator
• .\Octo.exe push --package=D:\Packages\Big.1.0.0.0.nupkg --server=https://myoctopus --apiKey=API-123
• Check the temp folder (C:\Users\Administrator\AppData\Local\Temp\2)

As part of this issue, consider that it is surprising anything is being persisted to a location other than the configured Octopus home directory.
