Figure what to do about algorithm_globals

[woodsp-ibm]

The algorithms, since Aqua days, all used/relied on a central RNG in algorithm_globals which can be seeded for reproducibility. This file is in Qiskit in qiskit.utils and the code here still refers to that. While the file there is not deprecated it was really for the algorithms, hence its name, so I could see it being removed from Qiskit. Most likely we need that function moved/copied here but this will be a change for end users on what should be seeded so we need to figure how to move forwards with this.
