Componentize TemperedLB #2485
Description
What Needs to be Done?
- Identify and isolate the dependencies of TemperedLB on the rest of VT.
- Refactor TemperedLB to use abstract interfaces for communication and termination detection.
- Provide default MPI-based implementations for these interfaces.
- Package TemperedLB (and its dependencies) as a standalone component/library.
- Document usage and integration steps for users.
