RS: refresh service upon init failure

Browse source 
When a service fails to initialize, RS exits the service. When injecting
faults this is undesired behavior. With this patch, we're going to assume
that when starting services with the -b flag (no binary exponential
offset), we don't want to exit the service but simply restart the
initialization.
