When a data frame analytics job is stopped because of a call to the _stop API, if the process is running it is killed. Depending on the OS, it may take some time to delete all the used named pipes. This means that in a scenario where the job is restarted immediately after it is possible that the old named pipes are used which results to the new process not properly communicating with java. This has been the underlying issue of elastic#70698 and elastic#67581. This commit fixes it by using unique identifiers for the named pipes. Closes elastic#70698
