Fingerbank collector is always set to "COLLECTOR_CLUSTERED" => "true", leads to warning level log noise if not in a cluster

[heapdavid]

It's not possible to disable fingerbank collector clustering in conf/fingerbank.conf, as clustering is enabled and hard-coded in /usr/local/fingerbank/collector/set-env-fingerbank-conf.pl

...
my %TO_SET = (
    "FINGERBANK_API_KEY" => $Config{upstream}->{api_key},,
    "COLLECTOR_DELETE_INACTIVE_ENDPOINTS" => $Config{collector}->{inactive_endpoints_expiration} . "h",
    "COLLECTOR_ARP_LOOKUP" => is_enabled($Config{collector}->{arp_lookup}) ? "true" : "false",
    "COLLECTOR_QUERY_CACHE_TIME" => $Config{collector}->{query_cache_time} . "m",
    "PORT" => $Config{collector}->{port},
    "COLLECTOR_ENDPOINTS_DB_PATH" => $COLLECTOR_ENDPOINTS_DATA_FILE,
    "COLLECTOR_ENDPOINTS_CACHE_PATH" => $COLLECTOR_ENDPOINTS_CACHE_FILE,
    "COLLECTOR_IP_MAPS_DB_PATH" => $COLLECTOR_IP_MAPS_FILE,
    "COLLECTOR_DB_PERSISTENCE_INTERVAL" => $Config{collector}->{db_persistence_interval} . "s",
    "COLLECTOR_CLUSTER_RESYNC_INTERVAL" => $Config{collector}->{cluster_resync_interval} . "s",
    "COLLECTOR_CLUSTERED" => "true",
    "GOGC" => "100",
    "GODEBUG" => "gctrace=0",
    "HTTP_PROXY" => fingerbank::Util::get_proxy_url("http"),
    "HTTPS_PROXY" => fingerbank::Util::get_proxy_url("http"),
    "COLLECTOR_CONTACT_PEERS" => (join ",", map{ $_->{management_ip} } @{get_servers()}),
    "COLLECTOR_ODA_PEERS_DISCOVERY_URL" => "http://localhost:22226/api/v1/pfconnector/all-fingerbank-collector-endpoints",
);
...

leading to warning log lines:
