### What should we add? The `CouplingMap` class in `/qiskit/transpiler/coupling.py` accepts a coupling list for initialization. The coupling list is expected to be a sequence of pairs of coupled qubits....

Allow passing numpy array to `PyDiGraph::extend_from_edge_list`

### What is the expected enhancement? Per current api, one way to extend an existing graph is to use the `PyDiGraph::extend_from_edge_list`. This method expects a list of tuples. The enhancement...
