* [JENKINS-43496] - Add handling of the null Node#createComputer() result.

it is a follow-up to https://github.com/jenkinsci/jenkins/pull/2836#discussion_r110604865

De-facto many Cloud plugins return `null` in `Node#createLauncher()`, but it has never been documented.
In order to prevent possible API misusages in the future, I have added annotations and fixed handling of the extension point in `AbstractCIBase#updateComputer()` which may fail in the case of `null` or `RuntimeException` in the Node implementation.

[JENKINS-38527] - Prevent NullPointerException in Slave#createLauncher() and add cause diagnostics (#2923)

* [JENKINS-38527] - Prevent NullPointerException in Slave#createLauncher() and add cause diagnostics

The original issue comes from the isUnix() unboxing, but we can also get into an issue later if we pass a null Channel instance to the logic.
This change adds some diagnostics which discovers potential root causes of such potential NPEs due to the race conditions with Computer reconnection

* [JENKINS-38527] - Also handle cases when Channel#isClosingOrClosed() as @stephenc suggested
