Comment 1 for bug 1202809

I need to write some upgrade tests that will benefit from having this. In
particular, I could use a testing server to verify that different upgrade
paths are correctly identified by the client.

As discussed today, the following changes are probably needed:
- Add another command line flag to accept self-signed certificates
- Add a command line flag to avoid the download server being killed by the
  lifecycle management process (this is to avoid the a new process being
  launched later using the command line without the option to accept the
  self-signed certificates).
