<p>Specfies how many restart attempts to make before migrating the failed service.</p>
<p>Note that these are consecutive attempts.
If the value is set to 6, and the service restart fails 5 times before succeeding, but then fails again later,
it will not instantly migrate. Each failure gets its own count of restart attempts.</p>
<p>A value of 0 is identical to setting {@link #getRestartOnFailure} to false. A value of -1 indicates the service
should <i>never</i> be migrated; instead, it will be restarted until it either works or the server shuts down.</p>
