Improve network boot troubleshooting documentation and initramfs scripts

Browse Source 
Update NETWORK-BOOT-TROUBLESHOOTING.md to clarify the boot process and emphasize the need to disable PXE before rebooting to ensure EEPROM updates are applied. Enhance initramfs scripts to improve DHCP lease acquisition and capture the device's IP address more reliably. Add a revision tracking feature to the initramfs build process for better version control. Modify provisioning-client.sh to ensure proper reboot handling after deployment and backup actions.
