Subject: T5150: initial implementation of new Kernel/Zebra route-map support

It is possible to install a route-map which filters the routes between routing
daemons and the OS kernel (zebra)

As of now this can be done by e.g.
* set protocols ospf route-map foo
* set protocols ospfv3 route-map foo
* set protocols bgp route-map foo

Which in turn will install the following lines into FRR
* ip protocol ospf route-map foo
* ipv6 protocol ospf6 route-map foo
* ip protocol bgp route-map foo

The current state of the VyOS CLI is incomplete as there is no way to:
* Install a filter for BGP IPv6 routes
* Install a filter for static routes
* Install a filter for connected routes

Thus the CLI should be redesigned to close match what FRR does for both the
default and any other VRF

* set system ip protocol ospf route-map foo
* set system ipv6 protocol ospfv3 route-map foo
* set system ip protocol bgp route-map foo
* set system ipv6 protocol bgp route-map foo

The configuration can be migrated accordingly. This commit does not come with
the migrator, it will be comitted later.
