k3s_server: add kube_vip_bgp_peers parameter (#599)

Browse Source 
With the kube_vip_bgp_peers it is possible to define
multiple BGP peer ASN & address pairs for kube-vip.

Sample:

```
kube_vip_bgp_peers:
  - peer_address: 192.168.128.10
    peer_asn: 64512
  - peer_address: 192.168.128.11
    peer_asn: 64512
  - peer_address: 192.168.128.12
    peer_asn: 64512
```

It is possible to merge further lists with kube_vip_bgp_peers__*
parameters.

Sample:

```
kube_vip_bgp_peers__extra:
  - peer_address: 192.168.128.10
    peer_asn: 64512
kube_vip_bgp_peers:
  - peer_address: 192.168.128.11
    peer_asn: 64512
  - peer_address: 192.168.128.12
    peer_asn: 64512
```

This will result in the following list of BGP peer ASN & address pairs:

```
- peer_address: 192.168.128.10
  peer_asn: 64512
- peer_address: 192.168.128.11
  peer_asn: 64512
- peer_address: 192.168.128.12
  peer_asn: 64512
```
