…ic#67937) Now that data frame analytics jobs can be resumed straight into the inference phase, we need to ensure data counts are persisted at the end of the analysis step and restored when the job is started again. This commit removes the need for storing the progress on start as a task parameter. Instead, when the task gets assigned we now restore all stats by making a call to the get stats API. Additionally, we now ensure that an allocated task that hasn't had its `StatsHolder` restored yet is treated as a stopped task from the get stats API, which means we will report the stored stats.
