k3s_server_post: add cilium_bgp_neighbors parameter (#579)

Browse Source 
With the cilium_bgp_neighbors parameter it is possible to define
multiple BGP peer ASN & address pairs for Cilium.

Sample:

```
cilium_bgp_neighbors:
  - 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 cilium_bgp_neighbors__*
parameters.

Sample:

```
cilium_bgp_neighbors__extra:
  - peer_address: 192.168.128.10
    peer_asn: 64512
cilium_bgp_neighbors:
  - 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
```
