Allow usage of mirror Jenkins Update-Center for downloading plugins
Sometimes (like today ... and many other times unfortunately) the main
Jenkins update center is down and you cannot build a Jenkins Docker image.
It is much better than to include the full base URL as JENKINS_UC_DOWNLOAD
so that the ENV variable can be overridden to point to an up-and-running site.
Example:
ENV JENKINS_UC_DOWNLOAD http://mirrors.clinkerhq.com/jenkins
diff --git a/plugins.sh b/plugins.sh
index f73a23a..f597a12 100755
--- a/plugins.sh
+++ b/plugins.sh
