Fix #1549: Check peer admin status from the BGP options
Browse files Browse the repository at this point in the history
To avoid an additional RPC request to check the actual configuration, we
can probably use the Shutdown flag under the BGP extended options:

```xml
<bgp-options>Preference LocalAddress AddressFamily PeerAS Multipath Refresh</bgp-options>
<bgp-options2>VpnApplyExport PeerSpecficLoopsAllowed</bgp-options2>
<bgp-options-extended>GracefulShutdownRcv Shutdown</bgp-options-extended>
```

This should be a more reliable way to check the admin status, instead of
incorrectly deducing the admin state from the operational state.
