Inspired by a recent [post](https://discourse.julialang.org/t/retrieve-current-solution-when-termination-status-is-time-limit/134464/7) where an LP is solved to suboptimality, I think it makes some sense to have relative gap/feasible solution/objective bound for LPs also. But it seems that Gurobi only has `MIPGap`, not applied to LPs. (no more comments unless I find that more needs are required in the future.)

I believe we can make the information of `solution_summary` richer.
