Add servername to tls options when connecting in DIRECT

[mceIdo]

This a recreation of this PR from the original repo, with adjustments to match the implementation in other proxy agents. I had an issue getting an ssl handshake failure error using a PAC based proxy configuration. Turns out servername must be provided to tls.connect(). I saw you had had it in your other "...-proxy-agent" so I just added the same here
