What should we add?

I realized that currently the CommutationChecker class can not handle Pauli Rotations if they are parameterized. In many cases our circuits are paramterized and the commutation relationships for this rotations are just the same ones as the ones for their generators. I propose to add this functionality into Qiskit. There are 2 ways to go about it. One would be to make the standard_gate_commuation dictionary bigger or to map the rotation gates to their generators.

I already have already implemented it for myself because I need it for my research so I would be happy to implement it for Qiskit.
