Sign rundeck-*.noarch.rpm to ease amazon linux cloud-config automated installation

Amazon Linux CloudInit packages installation based on "repo_additions + packages" blocks only supports signed RPMs.

The reason is that cloudinit's dist_repo_yum.py does not implement yet "gpgcheck=0".

The workaround is to install the "http://rundeck.org/latest.rpm" via the [runcmd] block but it is less elegant.

Sample of FAILING "repo_additions+packages" based Amazon Linux CloudInit script because Rundeck RPM is not signed:

#cloud-config




repo_additions:
 - source: "rundeck-release"
   filename: rundeck-release.repo
   name: "Rundeck - Release"
   baseurl: http://rundeck.org/repo/rundeck/1/release
   key: http://rundeck.org/repo/RPM-GPG-KEY-RunDeck.org
   enabled: 1




packages:
- rundeck




runcmd:
 - [service, rundeckd, start ]
 - [usermod, -a, -G, rundeck, ec2-user]

Sample of SUCCESSFUL Amazon Linux CloudInit script using the [runcmd] block:

#cloud-config




runcmd:
 - [rpm, -U, -v, -h, "http://rundeck.org/latest.rpm"] 
 - [yum, -y, install, rundeck]
 - [sh, -xc, "/etc/init.d/rundeckd restart"]

Context: we use CloudInit automated deployment of rundeck+jenkins+tomcat for training purpose: 1 jenkins + 1 rundeck + 2 tomcat per attendee.
