The previous jessie image had a broken cloud-init, which would use an
Ubuntu-specific 'nobootwait' argument when mounting disks. We now
override that in the image.
Fix#22549
Default distro is jessie, due to the support situation with Ubuntu
distros. Default ubuntu distro is wily.
Update the docs to reflect the recommended distros with kube-up, and to
encourage contributions for other distros.
Spot instances take a lot longer to run; wait up to 15 minutes for the
nodes to launch when we're using spot instances. (Previously we were
waiting 5 minutes).
Once we've built the master, we can build kubeconfig. By doing so, if
we time out waiting for the nodes, the system is still configured
correctly.
In particular, spot instances can be slow to launch.
Related to issue #21200
I think we should probably leave this undocumented for now, until we
have a better way to launch multiple sets of nodes, but it's great for
cost savings while testing!
Fix#21200
m3.large for > 150 nodes.
t2.micro often runs out of memory. The t2 class has very
difficult-to-understand behaviour when it runs out of CPU. The
m3.medium is reasonably affordable, and avoids these problems.

Issue #18975
Otherwise we risk services coming up on the master before the backing
volume is ready.
If we then see the master-pd is already mounted, don't try to remount
it.
Issue #21155
If the ephemeral volume is present and mounted, don't try to reinitialize
them.
Don't block the boot if the ephemeral volume is corrupt / missing -
this enables us to cope with a stop/start & presumably also corruption.
In this case, we'll reformat the ephemeral storage.
Fix#21157
This is so we have the same behaviour as on GCE.
This also lets us change the bootstrap script or the config, which is
nice. Instance data is immutable on AWS once it is booted.
Fix#21150
We were assuming the PROJECT env var was set, which the e2e tests do.
But PROJECT is normally not set on AWS (it is set on GCE); this broke as
part of the harmonization.
Revert to the pre-existing behaviour here, where we use "aws_" as the
prefix.
Fix#21141
Fix script for case when neeed to setup cluster
in an existen VPC and subnet with ip mask example: 10.0.0.0/8.
Fixed bug to detect ip of master if provided MASTER_RESERVED_IP.
For some reason detecting master ip was moved to volumes and only when MASTER_RESERVED_IP=auto.
If specify IPv4 for MASTER_RESERVED_IP like `52.1.1.1`, than we could
not detect ip even during last steps of setuping cluster.
step the KUBE_MASTER_IP is reseted because there are no tag for the
volume.
