Docker needs 10s at least for containers to be allowed to shut down,
so allow 15s maximum between SIGTERM and SIGKILL.

This allows plain `swarm init` to work. We do not support multi
node clusters yet as there is no way to reqach this address from
externally at present.

Use `make DOCKER_VERSION=xxx` to override version. Note that
as install process and packaging may vary this may not work.
Use `make DOCKER_EXPERIMENTAL=0` to build from either release
binaries, if version is a final release or test binaries for
release candidates.
Building experimental is still the default.

This adds a new notify channel to the transfuse protocol. It is not
optional yet but could be made to be optional. A notify protocol and
notify channel are required because writing FUSE response messages to
the FUSE device has different semantics from writing asynchronous
notifications. In particular, response message writes only error on
malformed messages, do not take locks, and do not block. In contrast,
asynchronous notifications can error under normal conditions
(e.g. invalidating a cache entry that doesn't exist), can take locks
during the write call, and can block.
If responses and notifications occur in the same thread, the file system
can become deadlocked when syscalls lock resources waiting for a
response and a notification is written that blocks attempting to acquire
those same locks. The response that would unlock the contended lock
could be queued behind the notification write but the notification write
can't unblock until the response is written in the future. This patch
enables file systems to avoid that fate by offering a secondary channel
on which to send notifications.

As arm will not be a desktop edition, we will not need to
try to fix these. We do need `diagnostics` though, the
vsock code however is not cross building, needs to be fixed
or made conditional.

Not really required as ports exposed on localhost. If users
want to connext to VM ports they can use the IP address, as
this is discouraged. llmnr names are very slow to access,
so not nice to use.

See #305#301
This sets AWS to use the amazon ntp pool, windows to do nothing,
mac uses ntp it gets from DNS. Azure currently uses default pool,
this probably needs fixing.
