Support restoring from a checkpoint when starting containers

[pronvit]

Currently if you pass checkpoint parameters to container.start() call, they will be sent as POST data and you'll get "starting container with non-empty request body was deprecated since v1.10 and removed in v1.12" error.

These parameters must be passed in url, i.e.

path: '/containers/' + this.id + '/start?checkpoint='+encodeURIComponent(checkpoint)+'&checkpoint-dir='+encodeURIComponent(checkpointDir)+'&'

You can call container.start() using "_query" option.
Something like: container.start({'_query': {'checkpoint': ...}})

Thanks, didn't know about the _query option.

Soon I will probably default container.start options to query/url instead of body, if you don't send _query.
This way it won't be a breaking change, eliminating the necessity to use it in this endpoint.

I tried this "_query" options, it doesn't work for me, there is still the deprecation error.

@apocas: I really need to pass options to container.start(), any progress on this issue?

Closing this one (shouldn't be an issue nowadays), reopen if needed.
