…astic#46721) When the stop API is called while the task is running there is a chance the task gets marked completed twice. This may cause undesired side effects, like indexing the progress document a second time after the stop API has returned (the cause for elastic#46705). This commit adds a check that the task has not been completed before proceeding to mark it so. In addition, when we update the task's state we could get some warnings that the task was missing if the stop API has been called in the meantime. We now check the errors are `ResourceNotFoundException` and ignore them if so. Closes elastic#46705 Backports elastic#46721
