CLI support to change boot order

[jovatn]

Description

Infix 25.01 added YANG RPC support to change boot order.
It would be nice to have corresponding support via CLI, e.g., to make a manual roll-back after an upgrade.

Perhaps like this.

admin@infix-ad-00-00:/> show software
BOOT ORDER
primary secondary net 

NAME      STATE     VERSION                DATE                     
primary   booted    v25.03.1               2025-04-25T11:36:26+00:00
secondary inactive  v25.01.0               2025-03-11T14:41:50+00:00
admin@infix-ad-00-00:/> set boot-order secondary primary net
BOOT ORDER
secondary primary net 
admin@infix-ad-00-00:/>

This should be implemented by calling the RPC with sysrepocfg not straight fw_setenv for two reasons:

1. The RPC has support for U-Boot and grub already
2. Its the right thing to do.
