…c#67623) If a DFA job is stopped while in the inference phase, after resuming we should start inference immediately. However, this is currently not the case. Inference is tied in `AnalyticsProcessManager` and thus we start a process, load data, restore state, etc., until we get to start inference. This commit gets rid of this unnecessary delay by factoring inference out as an independent step and ensuring we can resume straight from that phase upon restarting a job. Backport of elastic#67623
