PDLP parameters and deprecated fields

[Alan Walker]

Hi,

All the documentation I can find for setting PDLP parameters suggests code that gives deprecation warnings.  Here's my setup code and then the results I'm seeing.  MacOS 14.4.1, Python 3.12, OR Tools 9.15.6755

self.solver = pywraplp.Solver.CreateSolver("PDLP")
self.solver.SetSolverSpecificParametersAsString(
'termination_criteria {eps_optimal_relative: 1e-3 eps_optimal_absolute: 1e-3}')
