Additional parameters for 'qiskit.visualization.plot_circuit_layout'

[PetarJurcevic]

What should we add?

Currently the function highlights the layout of a circuit transpiled for a given target backend.

Useful additional features/options would be:
(coloring is just a suggestions)

• color non-used parts in grey
• color used parts in green
• pass a list of (user-defined) bad qubits/gates and high-light those in black if not used in circuit and in red if used in circuit
• pass a list of specific quantum operations to be highlighted (example only highlight physical gates gates such as x,sx, zz,zx, measuremetns etc, but not barriers, delays
• pass a list of specific quantum operations to be ignored (highlight everything but these operations, for example ignore barriers, but still highlight delays instructions
• scaling feature to change graph size
