I've observed networking between ec2 instances not start working for
somewhere between 40-50 seconds earlier today which caused the test to
fail despite the fact that everything came up properly eventually.
Upping to 90 seconds should better cope with the surprises Amazon has to
offer.
This is particularly important for the image availability pre-check
because without it we don't detect that the image is in-fact unavailable
when it doesn't exist and the 404 results in a error from bzip2.
The build host will start generating production ami disk images so to
simplify the next step this script can automatically fetch them from
that location by version. The default sticks with the existing 'master'
versioning scheme. Added logging and turned off -x by default to make
the output log more readable.
Removing the zip_and_ship script since it isn't useful with officially
built disk images and only works with locally built images and a very
particular ec2 host. A different long term automation scheme will have
to be found.
