Shift processes hidden within the repo to a ProcLib of generic processes

[phstratmann]

Objective of issue: Currently, many processes are being coded somewhere within the repo. I would suggest to shift them to a generic ProcLib.

Lava version:

• 0.3.0 (feature release)

Do you mean generic ProcLib of Lava or of lava-optimization?

[phstratmann]

Either would be fine. If it is viable that the processes may be re-used anywhere, I would suggest lava.
It is just strange to see processes anywhere else than in a ProcLib

I'm referring to processes such as in
src/lava/lib/optimization/solvers/generic/hierarchical_processes.py
src/lava/lib/optimization/solvers/generic/monitoring_processes/solution_readout/process.py
