Not fully sorted static routes in configuration.

[ak503]

If add some routes:

ip route 1.1.1.1/32 2.2.2.3
ip route 1.1.1.1/32 2.2.2.2
ip route 1.1.1.1/32 2.2.2.4

In config they sorted by gateway:

# do show running-config 
...
Current configuration:
!
frr version 8.1-dev
...
ip route 1.1.1.1/32 2.2.2.4
ip route 1.1.1.1/32 2.2.2.3
ip route 1.1.1.1/32 2.2.2.2

But when added ip route 1.1.1.1/32 2.2.2.1, he will added after ip route 1.1.1.1/32 2.2.2.4, but not after ip route 1.1.1.1/32 2.2.2.2:

# do show running-config 
...
Current configuration:
!
frr version 8.1-dev
...
ip route 1.1.1.1/32 2.2.2.4
ip route 1.1.1.1/32 2.2.2.1
ip route 1.1.1.1/32 2.2.2.3
ip route 1.1.1.1/32 2.2.2.2

There shouldn't be any functional impact here so this is purely cosmetic. It seems that with libyang these will be dumped in the same order they were entered, which might even be what we want.
