Add 'scan plans' to driver scan parameters for scheduled scan. Each 'scan plan' specifies the number of iterations to run the scan request and the interval between iterations. When a scan plan finishes (i.e., it was run for the specified number of iterations), the next scan plan is executed. The last scan plan will run infinitely. The maximum number of supported scan plans, the maximum number of iterations for a single scan plan and the maximum scan interval are advertised by the driver.
