Allow loading a `MinimumEigensolverResult` directly into the `MinimumEigenOptimizer`

4

### What should we add? The `MinimumEigenOptimizer` internally calls a minimum eigensolver and then postprocesses the obtained `MinimumEigensolverResult` in the context of the quadratic program that we try to solve....
