/**
 * A generic class that is used to set up specs for an elasticity strategy.
 *
 * A concrete `ElasticityStrategy` may use `ElasticityStrategySpec<T>` directly as the type for
 * its spec, or a class derived from this one, if, e.g., the transformation needs to be customized.
 *
 * Parameters that are defined by the output of the SLO are stored in `sloOutputParams`.
 * The type of this property determines if an elasticity strategy is compatible with a certain SLO.
 *
 * `staticConfig` should be used for other configuration data, which is not changed by the SLO.
 *
 * @note All elasticity strategy specs, no matter if they are define in TypeScript or not, must adhere to this class' layout.
 *
 * @param O The type of output parameters from the SLO/input parameters of the elasticity strategy.
 * @param T (optional) The type of `SloTarget` that the elasticity strategy can operate on.
 * @param C (optional) The type of `staticConfig` that the elasticity strategy accepts.
