refactor: split config into network, milestones, exceptions and dynamic-fees

[faustbrian]

Proposed changes

Sorts out the mess the whole configuration is at the moment by splitting it into network, fees and milestones. This means people no longer need to update their network config anymore.

Dynamic fees are specific to nodes and should not be included in milestones.

Types of changes

• Refactoring (improve a current implementation without adding a new feature or fixing a bug)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Checklist

• I have read the CONTRIBUTING documentation
• Lint and unit tests pass locally with my changes
