SecurityAnalysis: Reconfigure slack distribution outer loops per contingency using an extension

[jeandemanged]

Describe the current behavior

The same outer loops are used for basecase and all contingencies

Describe the expected behavior

Via a contingency extension, e.g. ContingencyParametersExtension ContingencyLoadFlowParameters, we can configure which contingencies should use either SlackDistribution or AreaInterchangeControl.
The operator strategies associated to the contingency, if any, would use the same outerloops as configured for the contingency.

For a start we propose the contingency extension to be created in OLF (and not core).

The extension would for a start support choosing:

• between SlackDistribution or AreaInterchangeControl,
• which balanceType should be used (on loads, generators, ...),
  but should server as a basis for other options in the future.

Describe the motivation

Customer request. Depending on the contingency type, either simulate FCR or FRR. (precision: OLF by itself will not check the contingency type, this is done outside OLF when creating/setting up the contingency extension).
