Connection Loss Improvement

[janxious]

What & Why

• Separate hello and authenticate functions
• Force connection close at end of write cycle so we don't hold open idle connections, which has the benefit of mostly removing the chance of getting hopelessly connection lost when either end of the connection innermittently drops

Required for all PRs:

• CHANGELOG.md updated
• Sign CLA (if not already signed)

@jasonroelofs pinging you since you wrote the first version

Looks good to me. Probably what I would have eventually done. I've tried a number of different ways to try to catch disconnects but haven't gotten anything to work reliably.

[janxious]

Yeah, we tried everything we could for a couple days, but it seems like the golang primitives are not built with dealing with disconnection in mind. We have some internal work on instrumental going that will allow for ack'ing, which will simplify disconnect detection and we can circle back round to this output. Thanks for looking!

you need to run go fmt ./... on your code

[janxious]

@Sparcc This has been go fmt ./...'ed. Thanks for the heads up.
