Cloud controller startup time

It seems like the cloud controller portion of Eucalyptus takes some time to initialise itself even on modern server hardware. While this may not directly be a bug, it can be confusing - I have been restarting it and reading logs to try and work out why it wasn't starting, when all I actually needed to do was wait (I don't have timing data for the first run to know if that was longer, but it reproducibly takes around 45 seconds to finish loading and listen on port 8443 on an HP DL385G2.

I did wonder if some of this was down to error messages about not being able to load http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd but it doesn't get any quicker if I nullroute java.sun.com (the machine in question is behind a firewall that would silently eat outbound packets to internet hosts).

I think it might be useful to have the init script's start action mention that it might be a minute or two until the service is fully started.
