Bulk cleanup of code in hudson.cli.

Address quiet period edge case (???)

* Add 'smoke-test' JUnit Category [JENKINS-53925]

* Update test-annotations version to 1.3

* Use org.jvnet.hudson.test.SmokeTest

* Try to clarify the message

Key points:
A. We aren't changing the remote update site
B. It's probably possible for this code to forget an ignore if you follow this process:
 
1. suppress a warning for plugin-x-warning-y
2. disable plugin-x
3. suppress a different warning
4. reenable plugin-x

* Trying to clarify where the warnings appear

* incorporating feedback from daniel
