+Specify whether a workflow step should request preemptible (e.g. AWS Spot market) instances.  Such instances are generally cheaper, but can be taken back by the cloud provider at any time (preempted) causing the step to fail.  When this happens, Arvados will automatically re-try the step, up to the configuration value of @Containers.MaxRetryAttempts@ (default 3) times.
