Use jenkins.io infra.buildPlugin() in Jenkinsfile

Simplifies the Jenkinsfile dramatically, provides multi-platform execution
(Windows and Linux), runs on my Jenkins docker instance (by importing the
same pipeline library repository into the parent folder as is used by
jenkins.io), runs plugin compatibility tests on Jenkins 2.32.2, allows
easy "replay", and makes it easier for jenkins.io administrators to add
functionality to many jobs at once by changing the pipeline library,
rather than changing all the job definitions.

Intentionally retries failing tests, since some of the credentials
tests in my private environment are unreliable due to hosting provider
reliability issues.
