Add some helpers to edit the boot-config for Aboot based products. Calling set_default_boot will now set SWI and SWI_DEFAULT to the next image to boot. Upon boot the SWI value gets overriden by SWI_DEFAULT. This mimic the behavior that grub has.

- What I did
Add some helpers to edit the boot-config for Aboot based products.
Calling set_default_boot will now set SWI and SWI_DEFAULT to the next
image to boot. Upon boot the SWI value gets overriden by SWI_DEFAULT.
This mimics the behavior that grub has.
- How to verify it
A change from sonic-buildimage in boot0 is required to properly test.
However the logic here can be tested by looking at the content of boot-config after running set_next_boot and set_default.
