Security Analysis: custom redistribution of injections lost by the contingency

[jeandemanged]

Describe the current behavior

When a contingency trips an injection and slack distribution enabled (or area interchange control), the missing active power is distributed using the configured balance type.

Note: done in advance of the Newton-Raphson for performance reason, see here in v1.12.2.

Describe the expected behavior

OLF provides a way to configure this redistribution externally via plugin mecanism (ServiceLoader).

Describe the motivation

Customer request: simulate FCR on particular contingencies by:

1. switching off AreaInterchangeControl, switching on "regular" slack distribution, (this part covered by SecurityAnalysis: Reconfigure slack distribution outer loops per contingency using an extension #1091)
2. (this issue) before launching the first post-contingency NR, instead of just doing a distribution over the entire component as it is done now, the injection lost by the contingency is spread over the areas according to areas participation factors (OLF doesn't know about this logic, supported by the plugin, other OLF users may build their own plugin with their own logic).
