* Added a note to teach users how to access a list of available IBM Q backends * Having two notes next to eachother looks visually bad so I just merged it with the previous note

Title:
Qubit tapering
Summary:
Adds a tutorial for using the qubit tapering functionality of PennyLane. The tutorial explains the theory and showcases a step-by-step workflow to generate symmetry operators, apply them to a molecular Hamiltonian such that it acts trivially on some qubits and taper-off those qubits by replacing them with a set of generated optimal eigenvalues. The resulting Hamiltonian acts on a fewer number of qubits. The process of reducing the number of qubits in the reference Hartree-Fock state is also explained.
