Add methods to get more statistics from the CQM object

1

It would be nice to have methods to quickly get some statistics about the CQM model. These are my wish list: ``` cqm.num_variables cqm.num_binaries cqm.num_integers cqm.num_discretes cqm.num_linear_constraints cqm.num_quadratic_constraints cqm.num_le_ineqaultiy_constraints cqm.num_ge_ineqaultiy_constraints...

More information is needed when user define constraints that has `BinaryQuadraticModel` as RHS ``` x = dimod.Binary('x') y = dimod.Binary('y') cqm = dimod.CQM() cqm.add_constraint(x
