*
* @param plugin
* A pointer to an uninitialized plugin. The plugin will be
* configured as a restart plugin.
* @param max_retries
* The maximum number of times to retry the operation before giving
* up on the transfer. If this value is less than or equal to 0,
* then the restart plugin will keep trying to restart the operation
* until it completes or the deadline is reached with an unsuccessful
* operation.
* @param interval
* The interval to wait after a failures before retrying the transfer.
* If the interval is 0 seconds or GLOBUS_NULL, then an exponential
* backoff will be used.
* @param deadline
* An absolute timeout. If the deadline is GLOBUS_NULL then the retry
* will never timeout.
