constraint filtering in large-scale security-constrained unit commitment.

Fields
------
- `time_limit`:
the time limit over the entire optimization procedure.
- `gap_limit`:
the desired relative optimality gap. Only used when `two_phase_gap=true`.
- `two_phase_gap`:
if true, solve the problem with large gap tolerance first, then reduce
the gap tolerance when no further violated constraints are found.
- `max_violations_per_line`:
maximum number of violated transmission constraints to add to the
formulation per transmission line.
- `max_violations_per_period`:
maximum number of violated transmission constraints to add to the
formulation per time period.
