♻️ director-v2 settings refactoring

[GitHK]

What do these changes do?

This is the second pass at refactoring the director-v2's settings. My objective here was to move them. I would delay other improvements for another PR.
This already helps a lot, especially if some part of the dynamic-scheduler needs to ne extracted out of the director-v2.

• ♻️ added new module core/dynamic_services_settings where all the settings were catalogued and split
• ⚰️ removed unused dynamic scheduler settings

Bonus:

• 🐛 trying to address flaky fixture in director-v2 integration testing

• followup to ✨ dynamic-sidecar receives prometheus metrics networks if defined ⚠️ #4986
