Deprecated StateLogger

[juan43ramirez]

Bug

The StateLogger in cooper.utils.state_logger.py is not compatible with the latest version of Cooper's dev branch.

It assumes that a Formulation will have a ConstrainedMinimizationProblem as an attribute:

cooper/cooper/utils/state_logger.py

Lines 42 to 48 in 3e0aa6f

	for metric in self.save_metrics:
	if metric == "loss":
	aux_dict[metric] = formulation.cmp.state.loss.item()
	elif metric == "ineq_defect":
	aux_dict[metric] = deepcopy(formulation.cmp.state.ineq_defect.data)
	elif metric == "eq_defect":
	aux_dict[metric] = deepcopy(formulation.cmp.state.eq_defect.data)

This is not the case since merging #56.

Steps

Update the interface of StateLogger. store_metrics should receive a CMPState or the unpacked metrics.
