Add support for --health-start-period in Compose/Stack file

[vide]

Description

With Docker CE 17.05 there is the brand new --health-start-period option for a service, implemented with moby/moby#28938. But there is no such option available in a Compose/Stack file, so we can properly manage it with a YAML file.

I think I'm not qualified to propose the key name that should eventually implemented in theCompose file but I'd say that start_period, under healthcheck could be a good name.

Should this be against the docker/compose project as opposed to the docker/cli?

@electrofelix Don't know, @thaJeztah pointed me to this repo. My request is that this config should be implemented in Stack and should be gracefully ignored in Compose

Having see this appear in CE, I was going to open a request in the compose project for it to be supported when I stumbled across this issue. Noticed that the code in this repo already supports a --health-start-period, but couldn't find any connection between as to where issues belong, so just a little confused as to whether I should only track this issue or log a separate one for the behaviour to be added to compose ahead for the 17.06 release which I'm guessing will be the first stable release to include this?

Is there an issue in compose project?

ping @shin- do you know? ^^

docker/compose#4646 is the closest we've had, but now that the feature's in engine we can open a new ticket.

@thaJeztah and what about Stack, which is where the issue is more relevant? Right now I have to deploy a stack with a yaml file and then issue a docker service update ASAP to update the healthcheck-start-period so my service can actually start and not be killed over and over by Swarm
