Rework BOOT LED handling. There is currently one legacy implementation for BOOT LED from Status Led API. This work on ancient implementation used by BOOTP by setting the LED to Blink on boot and to turn it OFF when the firmware was correctly received by network. Now that we new LED implementation have support for LED boot, rework this by also set the new BOOT LED to blink and also set it to ON before entering main loop to confirm successful boot.
