Subject: [PATCH] pythonPackages.qiskit-ignis: init at 0.2.0

Qiskit Ignis is a toolbox for quantum hardware verification,
noise characterization, and error correction.

This commit follows the new Qiskit scheme of breaking one large package
into smaller packages (terra, aer, etc), and then having a single
meta-package "qiskit" that comprises them.
