Extension to be merged into life-cycle-manager

This new LCM code is able to load/update the bootloader from github.
The new bootloader is able to count the amount of short power cycles (<1s)
The boot loader conveys the count to the loaded code using the rtc.temp_rom value
User code is allowed the values from 1-4

• 1 : this is a normal boot
• 2-4: users choice in user code (communicate 3 to user or risk a bit and use 2, 3 and 4 separatly)

If count > 4 the bootloader launches LCM otamain.bin in rom[1]

For these values the behaviour is controlled through the sysparam string ota_count_step.
The default value of 3 reduces the chance of user misscounting and triggering something else than intended.

If ota_count_step=="3"

• 5-7: check for new code (communicate 6 to user)
• 8-10: erase wifi info (communicate 9 to user)
• 11-13: factory reset ( (communicate 12 to user)
• 14-16: factory reset and join LCM_beta (communicate 15 to user)

If ota_count_step=="2"

• 5-6: check for new code (communicate 5 to user)
• 7-8: erase wifi info (communicate 7 to user)
• 9-10: factory reset ( (communicate 9 to user)
• 11-12: factory reset and join LCM_beta (communicate 11 to user)

If ota_count_step=="1"

• 5: check for new code (communicate 5 to user)
• 6: erase wifi info (communicate 6 to user)
• 7: factory reset ( (communicate 7 to user)
• 8: factory reset and join LCM_beta (communicate 8 to user)

Missing or other ota_count_step values will be interpreted as 3
