Deployment task is read from wrong place and falls back to default

[Otto Vehviläinen]

It seems like all the providers are trying to read the task from wrong place. Capistrano, BundlerCapistrano and Fabric all have

def task
  name = custom_payload && custom_payload["task"] || "deploy"
  ...
end

where custom_payload comes from DefaultProvider as

def custom_payload
  @custom_payload ||= data["deployment"]["payload"]
end

However the deployments api has the task attribute directly under deployment and not in the payload.
