Update plugin existance test for both hpi and jpi

For some reason, after jenkins restarted, it renames .hpi to jpi. e.g. ant plugin
Because of this, puppet will install the plugin everytime it runs.
Added notify relationship between jenkins::config ~> jenkins::service

When the jenkins::config is changed (changing HTTP_PORT for example) the service was not refreshed.

This fixes this issue.
