Expected behavior

Users generally expect Swift NIO not to fail with internal assertions and fatalErrors they couldn't catch.

Actual behavior

Fatal error: Invalid FSM transition attempt: state complete, input connectTimeoutElapsed: file swift-nio/Sources/NIO/HappyEyeballs.swift, line 417
Illegal instruction: 4

Steps to reproduce

Compile and run the attached code against the master.

If possible, minimal yet complete reproducer code (or URL to code)

@tomerd
update docs generation script to work better with selinux (apple#187)
780e3a2 
motivation: docs scripts is broken on selinux due to restriction on ssh-agent

changes:
* change the jazzy workspace to a directory accessible by the CI node so we can push from the agent instead of from the docker container
* dont remove older docs when pushing new ones
* add version information and source links
