Code to send diagnostic messages about cloud print proxy. Currently diagnostic messages are sent if the print system fails to initialize (this can happen on Windows if the XPS Framework is not installed on XP) as well when printer registration fails because we could not get the capabilities for the printer.

BUG=None
TEST=None
