service: add options RestartPreventExitStatus and SuccessExitStatus

In some cases, like wrong configuration, restarting after error
does not help, so administrator can specify statuses by RestartPreventExitStatus
which will not cause restart of a service.

Sometimes you have non-standart exit status, so this can be specified
by SuccessfulExitStatus.
