Misc dynamic pipeline improvements

[schustmi]

Describe changes

• Don't restart the Kubernetes orchestrator pod for dynamic pipelines
• Improve placeholder run handling and prevent some potential issues
• step.map(...) and step.product(...) now return a future object instead of a list of futures of the step invocations. This future behaves similar to a list, but also has an unpack() method to achieve similar behaviour to tuple unpacking.
