frr: return AS0 if AS_PATH length is zero 
Local prefixes usually do not have an AS_PATH:
```
vtysh -c "show bgp ipv4 unicast 10.10.10.10 json" | jq '.paths[].aspath'
{
  "string": "Local",
  "segments": [],
  "length": 0
}
```

Set AS0 as a temporary solution when AS_PATH length is zero. This
avoids parser failures for local prefixes, though ideally we should
use the device's actual ASN (see TODO in code).

frr: set default values for optional next-hop fields 
The metric and used fields might not be returned, causing the parser to
fail if they are not present. The absence was observed in FRR 10.4.1
with a multipath IPv6 route that has two next-hops (one GUA, one LL):
```
$ vtysh -c "show bgp ipv6 unicast 2003::/19 json" | jq '.paths[].nexthops'
[
  {
    "ip": "2a0d:2146:bdff:120::1",
    "afi": "ipv6",
    "scope": "global",
    "linkLocalOnly": false,
    "length": 32,
    "metric": 0,
    "accessible": true
  },
  {
    "ip": "fe80::3e61:408:1e3e:cff0",
    "afi": "ipv6",
    "scope": "link-local",
    "length": 32,
    "accessible": true,
    "used": true
  }
]
[
  {
    "ip": "2a0d:2146:bdff:120::1",
    "afi": "ipv6",
    "scope": "global",
    "linkLocalOnly": false,
    "length": 32,
    "metric": 0,
    "accessible": true
  },
  {
    "ip": "fe80::3e61:408:1e3e:cff0",
    "afi": "ipv6",
    "scope": "link-local",
    "length": 32,
    "accessible": true,
    "used": true
  }
]
```

Tested: Query a prefix with multiple next-hops where the metric or used
attributes are missing on one of them.
