Openqaoa

This version fixes some breaking changes appearing with qiskit 0.45

This version brings two main changes:
* Temporary removing pyquil from the openqaoa meta package. Pyquil is still installable as a standalone package with `pip install openqaoa-pyquil`, it will not be included in `pip install openqaoa` until the issue has been fixed - https://github.com/entropicalabs/openqaoa/issues/293
* Installation was made impossible by conflicting dependencies between pyquil and the rest of openqaoa
* We removed pyquil temporarily
* We will be updating pyquil and fixing breaking changes in the next release
* New problem class
* Binary Paint Shop Problem

This version brings the following changes:
* Fix QPU tests due to provider changes
* Fix `backend_qpu`/`device.backend_device` duplicate
* Compatibility of QAOA and RQAOA with Azure Quantum sessions

This version fixes the version of `pyquil` to prevent breaking changes occuring with v4.0.0.

This version fixes an issue detecting the plugins when installing `openqaoa-core` from PyPI.

This new version brings an import change to OpenQAOA, separately installable plugins to access
different providers.
