[ixpmanager] Lifting sanity check for first ASN check up

[Alexander Kronenberg]

Hi Jasper,
Should it look like that:

    # Peer ASN == route's first ASN?
    if (bgp_path.first != <?= $int['autsys'] ?> ) then {
        bgp_large_community.add( IXP_LC_FILTERED_FIRST_AS_NOT_PEER_AS );
        accept;
    }

    # Skipping first ASN check for 65000
    if (<?= $int['autsys'] ?> == 65000) then {
        bgp_large_community.delete( IXP_LC_FILTERED_FIRST_AS_NOT_PEER_AS );
        accept;
    }

Where 65000 is an example of ASN.
