Whenever the "exec" task driver is being used, nomad runs a plug in that in time runs the task on a container under the hood. If by any circumstance the executor is killed, the task is reparented to the init service and wont be stopped by Nomad in case of a job updated or stop. This commit introduces two mechanisms to avoid this behaviour: * Adds signal catching and handling to the executor, so in case of a SIGTERM, the signal will also be passed on to the task. * Adds a pre start clean up of the processes in the container, ensuring only the ones the executor runs are present at any given time.
