    Automatically exclude patches on AIO-SX during backup

    Backup was including patch data on AIO-SX systems.
    This increased the size of backup significantly. This
    unnecessarily increased centralized storage and restore timing.

    Patch data will now no longer be collected during backup on
    AIO-SX systems.

    To override this behaviour the user can add the following:
    "-e exclude_patches=false"

    TEST PLAN
    PASS: Optimized B&R on AIO-SX system.
    * Repeat on patched and unpatched system
    * Patch data should not be present in either test
    PASS: B&R on AIO-SX system
    * Use "-e exclude_patches=false"
    * Patch data should be in backup
    PASS: B&R on non-SX system
    * Patch data should be in backup
    PASS: Optimized B&R on subcloud using dcmanager
    * patch data should not be in backup
