Gurobi interface (#19)

* feat: working gurobi interface * feat: add objective property * test: add test_change_of_objective_is_reflected_in_low_level_solver to gurobi_interface * fix: set proper verbosity at model initiation * test: add netlib tests for gurobi_interface * fix: get constr name * feat: implement set_linear_coefficients for gurobi_interface.Constraint * feat: implement set_linear_coefficients for gurobi_interface.Objective * feat: implement constraint.name property * feat: add _get_expression to gurobi_interface.Objective * fix: flake8 * fix: cplex -> gurobipy in conditional before TestMissingDependency
