Appscale stalls on startup

[GoogleCodeExporter]

When running appscale, occassionally the following will show up on the logs
and appscale fails to come up:

[Tue Nov 24 01:59:56 -0800 2009] Still waiting for that secret key...

The appscale-tools say:
Please wait for the controller to finish pre-processing tasks.

and when ctr-c'ed out of them:
^C./../lib/common_functions.rb:103:in `sleep': Interrupt
    from ./../lib/common_functions.rb:103:in `sleep_until_port_is_open'
    from ./../lib/common_functions.rb:101:in `loop'
    from ./../lib/common_functions.rb:101:in `sleep_until_port_is_open'
    from appscale-run-instances.rb:198

This is believed to be caused by a failed scp of the secret key from the user's 
box
to the head node. Have added in a check on the return value of scp (with the 
tools
failing if it's not zero) and a timeout on the scp itself (as if the box itself 
is
down, scp will take a while to return).

Tested and working with current version of appscale, will leave open until we 
are
certain this fixes the problem.

Raj still encounters the same problem but I am unable to repro it. Will return 
to
this problem later.
