Allow user to run custom graph on cluster

Registered by Alexey Shtokolov on 2016-02-20

As cloud operator I would like to run the custom set of deployment tasks on my cluster. I want to specify all tasks in yaml-file.

I want to have the special handlers to upload new graphs from file, to download and to override existed graphs. And special handler to execute selected graph on whole cluster or on the set of nodes.

Expected commands:
fuel graph list --env env_id
fuel graph upload --env env_id --type graph_type --file tasks.yaml
fuel graph download --env env_id --type graph_type --file output.yaml
fuel graph execute --env env_id --type graph_type [--node node_ids]

graph_type is unique for selected cluster.
