hello -

i'm creating some tests for my job dsl scripts and i'd like to be able to force my tests to fail if the plugins aren't installed in the test instance.

in order to do that, JenkinsJobManagement.setFailOnMissingPlugin would need to be made public. obviously i can work around this by creating a subclass in a javaposse.jobdsl.plugin package locally, but that seems kind of dirty.
