make start.config non-mutating, fix --kubeconfig handling

[liggitt]

Extension of #1128

@smarterclayton this is worthwhile to get in now:

• makes the 11,000,000 different ways of running openshift start testable
• lets you trigger external kubernetes mode with either --kubernetes=... or --kubeconfig=...
• prevents credentials in --kubeconfig from being sent to the wrong server if --kubernetes was also set and pointed somewhere else
• lays the groundwork for separating start into stages later (input stage, host calculation/defaulting stage, bootstrapping/cert generation stage, execute stage)

@deads2k review my commits?

[deads2k]

Well, my schedule definitely didn't include 2am... :)

[deads2k]

I like it. I just want to make sure I can launch it in an integration test and then I'd say it's good.

Authorization integration tests are needed and this fix makes it easy to do. By clearly splitting responsibilities in start.go, we were able to write a series of unit tests to catch edges, both on general defaulting and on the bindings of those config values to the command line.

That was a joke on the 11 million

See comments, otherwise this looks like an excellent refactoring, thank you David and Jordan

[liggitt]

comments addressed, squashed as much as I plan to (david's together for credit/blame, mine together for credit/blame, two small unrelated fixes as separate commits)
