Custom RoleManager

See original GitHub issue

Hello. In this doc page, the maintainers of Casbin seem to imply that you can choose/write your own RoleManager class. However, this seems to be hardcoded in. Is there a way to supply a custom class? Can one be made with relative ease?

set_role_manager() should be called before adding g policy rules.

    m = casbin.model.Model()
    m.add_def("r", "r", "sub, obj, act")
    m.add_def("p", "p", "sub, obj, act")
    m.add_def("g", "g", "_, _")
    m.add_def("e", "e", "some(where (p.eft == allow))")
    m.add_def("m", "m", "g(r.sub, p.sub) && r.obj == p.obj && r.act == p.act")

    a = db.Adapter(postgresql_engine)
    a.add_policy("p", "p", ["alice", "data1", "read"])
    a.add_policy("p", "p", ["bob", "data2", "write"])
    e = casbin.Enforcer(m, a)
    e.set_role_manager(db.MyRoleManager())

Will alice and bob make it into roles?
