indexer ports are not switched to TLS when node to node encryption is turned on

1. Create a 2 node cluster KV on node1 and n1ql + indexer on Node2
2. run the following on both the nodes:
curl -v -X POST -d 'external=inet_tcp,inet_tls' http://localhost:8091/node/controller/distProtocols -u Administrator:password
3. Execute the following on both the nodes:
curl -X POST -d 'afamily=ipv4' -d 'nodeEncryption=on' -u Administrator:password http://localhost:8091/node/controller/setupNetConfig
4. Run testssl.sh on following ports:
Defined by ns-server. Port 9104 is not used.

%% index service ports
?define_port(indexer_admin_port, indexAdmin, index, 9100),
?define_port(indexer_scan_port, indexScan, index, 9101),
?define_port(indexer_http_port, indexHttp, index, 9102),
?define_port(indexer_stinit_port, indexStreamInit, index, 9103),
?define_port(indexer_stcatchup_port, indexStreamCatchup, index, 9104),
?define_port(indexer_stmaint_port, indexStreamMaint, index, 9105),

Project
%% projector ports - depending on the cluster encryption setting,
%% projector hosts either an SSL or non-SSL endpoint.
%% Hence assigning the same port for both types.
?define_port(projector_port, projector, kv, 9999),
?define_port(projector_ssl_port, projector, kv, 9999, secure),

Test respond with - doesn't seem to be a TLS/SSL enabled server.
