Aaron Lehmann 06ebd4517d Service update failure thresholds and rollback
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.

Aaron Lehmann 56d92bfdff cli: Add more nil checking to service pretty-printer
Currently, if the service mode is not "global", this code assumes that
Replicated is non-nil. This assumption may not be true in the future.
Instead of making the assumption, explicitly check that Replicated is
non-nil before using it.

Similarly, for limits and reservations, enclose methods that read from
Limits and Reservations within checks that those fields are non-nil.

Brian Goff 20c5a9448d Add formatter for service inspect
Allows the user to use `pretty` as the format string.
This enables users to put custom format options into their CLI config
just like is supported for `docker ps` and `docker images`
