[from qiskit] Add Covariance Matrix Adaptation Evolution Strategy (CMA-ES) optimizer for VQAs

[ElePT]

What should we add?

Qiskit terra interface for CMA-ES which is a stochastic derivative-free numerical optimization algorithm, observed in arXiv:2111.13454 to be on par with and sometimes outperforming SPSA with appropriate hyperparameter tuning [^1].

[^1]: I would be more than happy to work on this.
