Task Spec should define a machineRef not a connection

[jacobweinstock]

The Task spec currently doesn't allow referencing a machine but requires the full connection details. Tasks should not require the full connection details. It should instead reference a machine like the Job spec does.

This was by design, though I don't recall the details. What's the motivation to change it?

[jacobweinstock]

The UX of jobs is nice. I dont need to add connection details per job. I could see the util in keeping the connection object in a task so that one off tasks can be defined without needing to have a machine CR or before one is created. But once a machine CR exists, having to define the connection details for every tasks is not ideal. Maybe tasks could take either a machine ref or connection details.

A mutually exclusive field with the connection field sounds quite flexible; I'd probably be in favor of that.
