refactor: massive jump toward a legit homestar runtime

[zeeshanlakhani]

• Adds runtime for singular workflows (multiple workflows incoming). Incldues:
  • workflow => Dag for sequential/promised and parallel compute
  • task scheduler (within workflow)
  • worker
  • integration between libp2p and workers for receipts and more
  • feature-gating ipfs for resources
  • adds retry/backoff for fetching resources
• moves us toward tracing's logging and adds logfmt-formatted logs
• removes much of early-early demo code

Issues closed:

• Captured Receipts #76
• Scheduler: Parallel vs Sequential Execution of Workflow Tasks #79
• Completed IPFS and libp2p Integration #86 (enough for now)
