Backend calibrations instantiation (qiskit-community#541)

* * Added methodology in BackendCalibrations so that we can instantiate without a backend. * * Added tests. * * Lint * Update qiskit_experiments/calibration_management/backend_calibrations.py Co-authored-by: Naoki Kanazawa <[email protected]> * Update qiskit_experiments/calibration_management/backend_calibrations.py Co-authored-by: Naoki Kanazawa <[email protected]> * * getattr * * Protected method. * * Merged BackendCalibrations into Calibrations. * * Renamed the control_config to control_channel_map * * Docstring for coupling map * Update qiskit_experiments/calibration_management/calibrations.py Co-authored-by: Naoki Kanazawa <[email protected]> * * List of basis gate library. * * Inst map updating. * * Default cal values. * * Operated qubits. * * Fix doc. * * Removed default_inst_map. * * Type hint. * * most_recent computation. * * Removed unnecessary check. * Update qiskit_experiments/calibration_management/calibrations.py Co-authored-by: Will Shanks <[email protected]> * * Docs. * * Docs. * * Backend name and version. * * Docs. * * Removed comment. * * update_inst_map * * Black. * * renamed lo_freq to drive_freq and meas_freq * * Renamed variables for consistency. * Update qiskit_experiments/calibration_management/calibrations.py Co-authored-by: Naoki Kanazawa <[email protected]> * * Docs. * * Robust name and version getting. * * Lint and tests. * * Reinstated default_inst_map * * Test fix. * * Updated tutorial. * * Test fix. * * Fix test. * * Fix stragling BackendCalibrations in docs.
