T6121: Extend service config-sync to new sections

Extend `service config-sync` with new sections:
 - LeafNodes: pki, policy, vpn, vrf (syncs the whole sections)
 - Nodes: interfaces, protocols, service (syncs subsections)

In this cae the Node allows to uses the next level section
i.e subsection

For example any of the subsection of the node `interfaces`:
  - set service config-sync section interfaces pseudo-ethernet
  - set service config-sync section interfaces virtual-ethernet

Example of the config:
```
set service config-sync mode 'load'
set service config-sync secondary address '192.0.2.1'
set service config-sync secondary key 'xxx'
set service config-sync section firewall
set service config-sync section interfaces pseudo-ethernet
set service config-sync section interfaces virtual-ethernet
set service config-sync section nat
set service config-sync section nat66
set service config-sync section protocols static
set service config-sync section pki
set service config-sync section vrf
```
