Decide if we want to fail if Indexer listens on *:9100 port after enforcing TLS

Summary:
Currently, we have a test that scans all ports to see if any services are listening on non-loopback address at non-ssl port after enforcing TLS.
One such port is indexer's 9100. After enforcing TLS, indexer seems to listen on this port on all addresses. ie;

ss -4anpe | grep "9100" | grep "LISTEN" 

returns

tcp    LISTEN     0      128       *:9100                  *:*                   users:(("indexer",pid=83917,fd=21)) uid:996 ino:192323307 sk:ffff97f84dcabe00 <->

it returns *:9100 .

Filing this to check if this is expected or if indexer must listen instead only on 127.0.0.1:9100 after enforcing tls.
