Remove max-active-runs and catchup

[aaazzam]

Bug summary

The deployment keywords max_active_runs: int and catchup: bool were part of an old API design for deployment concurrency that was never implemented. We have since opted for a different design, but these kwargs still exist throughout the codebase. This is causing several issues:

• Polluting the API surface
• Creating confusion in the documentation
• Potentially misleading developers about available functionality
