automl fit with starting points (#141)
* add starting point in fit

* add estimator best config

* add test

* add doc string

* when there are multiple points_to_evaluate in CFO, use the best one to start local search; after that use low cost partial config as the start point; then, remove the points whose performance is worse than the converged, and start local search from the remaining ones ordered by their performance.
