Qiskit Handle Qubit Loss Results (#726)

* Initial Generic Qiskit Backend

* Ensure metadata are strings

* added _azure_config method to generic

* format job.py

* convert qubit loss to "0" in qiskit output translation

* merge collided results

* format job.py again

* Keep both error and normalized results

* drop qubit-loss results for regular qiskit fields, but keep "raw" fields.

* undo remove line

* Revert "format job.py"

This reverts commit 8e85fb6.

* use np.round
