Refactor Pipeline parsing

[gsoltis]

• Avoid leaking the struct we parse to from JSON in the struct that we use in the remainder of the code
• Make the struct we use in the remainder of the code more semantically useful.
  • Parse out environment dependencies
  • Split task and topological dependencies
• Apply default outputs during parsing, rather than during use
• Rename Pipeline -> TaskDefinition and PipelineConfig -> Pipeline.

Note that the merge base is #951, which we ought to merge first, and then update this to be against main.
