DH-18424: Force websocket connections for 0.37.x+ Core servers

Testing
I tested the following scenarios on my Mac:

• Grizzly with Core+ 0.37.x (can use dev-grizzly2)
• San Luis with Core+ 0.37.x (can use dev-sanluis)
• Community http
• Community https (note -Dhttp.websockets=true needs to be set when starting the server)
  Example START_OPTS -Dhttp.port=444 -Dhttp.websockets=true -Dssl.identity.type=privatekey -Dssl.identity.certChainPath=/dev-certs/localhost.crt -Dssl.identity.privateKeyPath=/dev-certs/localhost.key. Also NODE_EXTRA_CA_CERTS needs to be set when using self signed SSL certs (see README).

NOTE: Would be good to test at least the first 2 items on Windows since the user originally had some Windows specific issues. I don't have a way to do this since my Windows machine does not have access to the VPN

I think @dsmmcken may be the only one with Windows now (unless @mattrunyon still has a Windows machine with VPN. David recently installed linux).
