This parameter controls the order of operations when rolling out an
update task. Either the old task is stopped before starting the new one,
or the new task is started first, and the running tasks will briefly
overlap.
This commit adds Rollout to the API, and --update-order / --rollback-order
flags to the CLI.

When UpdateStatus was not present, the empty values of the timestamps
would be present:
"UpdateStatus": {
"StartedAt": "0001-01-01T00:00:00Z",
"CompletedAt": "0001-01-01T00:00:00Z"
}
To fix this, make the timestamps pointers, so they can be set to nil
when they should not be shown.
Also make UpdateStatus itself a pointer, so an empty object does not
show up when there is no UpdateStatus.

Add the following options to "swarm init" and "swarm update":
- --max-snapshots: Retain this many old Raft snapshots in addition
to the latest one
- --snapshot-interval: Number of log entries between Raft snapshots
These options already existed in SwarmKit and the Docker API but were
never exposed in the CLI. I'm adding them here to fix this oversight.
--max-snapshots may be useful for debugging purposes and more
conservative users who want to store rolling backups of old versions of
the Raft state.
--snapshot-interval is most useful for performance tuning. The default
value of 10000 may not be ideal for some setups.
There is also a LogEntriesForSlowFollowers option that is not exposed. I
decided not to expose it along with these others because I don't think
it's generally useful (and I'm not sure what I would call the CLI flag).
But if people want, I can expose it for the sake of completeness.

Currently, there's no way to restart the tasks of a service without
making an actual change to the service. This leads to us giving awkward
workarounds as in
https://github.com/docker/docker.github.io/pull/178/files, where we tell
people to scale a service up and down to restore balance, or make
unnecessary changes to trigger a restart.
This change adds a --force option to "docker service update", which
forces the service to be updated even if no changes require that.
Since rolling update parameters are respected, the user can use
"docker service --force" to do a rolling restart. For example, the
following is supported:
docker service update --force --update-parallelism 2 \
--update-delay 5s myservice
Since the default value of --update-parallelism is 1, the default
behavior is to restart the service one task at a time.

This adds support for two enhancements to swarm service rolling updates:
- Failure thresholds: In Docker 1.12, a service update could be set up
to either pause or continue after a single failure occurs. This adds
an --update-max-failure-ratio flag that controls how many tasks need to
fail to update for the update as a whole to be considered a failure. A
counterpart flag, --update-monitor, controls how long to monitor each
task for a failure after starting it during the update.
- Rollback flag: service update --rollback reverts the service to its
previous version. If a service update encounters task failures, or
fails to function properly for some other reason, the user can roll back
the update.
SwarmKit also has the ability to roll back updates automatically after
hitting the failure thresholds, but we've decided not to expose this in
the Docker API/CLI for now, favoring a workflow where the decision to
roll back is always made by an admin. Depending on user feedback, we may
add a "rollback" option to --update-failure-action in the future.

restart-condition for services from "on_failure" to "on-failure".
Since GRPC does not support dashes in properties, this change
added a conversion when _setting_ the restart-condition.
However, when inspecting a service, no conversion took place
from the internal GRPC value, resulting in "on_failure" to
be shown.
This change updates the conversion to fix this, and removes
a "hack" that was previously used for this, now using a
Switch to compare to actual types.
Before this change:
docker service create --name web --restart-condition=on-failure nginx:alpine
docker service inspect --format '{{ json .Spec.TaskTemplate.RestartPolicy }}' web
{"Condition":"on_failure","MaxAttempts":0}
Afer this change:
docker service create --name web --restart-condition=on-failure nginx:alpine
docker service inspect --format '{{ json .Spec.TaskTemplate.RestartPolicy }}' web
{"Condition":"on-failure","MaxAttempts":0}
