QAOA compatibility with no dependencies from qiskit-algortithms

[TolisChal]

This PR migrates qaoa.py from qiskit-algorithms:

i) It adds qaoa.py and its dependencies from qiskit-algorithms
ii) It adds only the necessary for qaoa dependencies from qiskit-algorithms
iii) It migrates the source code from qiskit-algorithms following the paradigm of this PR: qiskit-community/qiskit-machine-learning#817

Thank you for making this draft.
FYI, Qiskit machine learning also migrated qiskit-algorithms for the same reason. I think their approach would be helpful.

Could you update readme.md to replace qiskit_algorithms?
