BZ 1070242 - don't create a agentinstall row if agent is deleted
BZ 1070242 - don't update agentinstall info unless the agent is installed
BZ 1070242 - put the file upload content under the as tmp dir and keep it unti we need it
BZ 1070242 - opps, have to put this back, other things that use upload need the file upload item name, not the file system name
