TKI - First phase

[NicoRenaud]

This PR is the result of the firs phase of the TKI project. It is (unfortunately) a large PR that combines different developments:

• The possibility to do QPE and iterative QPE with both qiskit and pennylane QPE and IQPE #85
• The possibility to do SA-OO-VQE with both qiskit and pennylane Refac saoovqe #87
• The removal of qiskit as a required dependency (through qiskit-nature) to compute the second quantization Unfreeze qiskit #90
• The introduction of new entries in qcschema to store the 2nd quantized Hamiltonian and its qubit mapped version Unfreeze qiskit #90
• The addition of new ansatz for qiskit thanks to Seenivasan Ansatz library #76
• A large refactoring of the code to simplify the structure Move secondq #92
