Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1312422

Description of problem:
When preparing to register a content host, installing the custom CA from the satellite via # rpm -Uvh http://sat6.lyletech.lab/pub/katello-ca-consumer-latest.noarch.rpm will restart a running docker service, resulting in any containers running on that service to stop

Version-Release number of selected component (if applicable):
katello-ca-consumer-latest.noarch.rpm

How reproducible:
always

Steps to Reproduce:

1)Configure docker repo

1. sudo tee /etc/yum.repos.d/docker.repo <<-EOF
   [dockerrepo]
   name=Docker Repository
   baseurl=https://yum.dockerproject.org/repo/main/centos/7
   enabled=1
   gpgcheck=1
   gpgkey=https://yum.dockerproject.org/gpg
   EOF

2) install docker

1. yum install docker-engine

3) start the service

1. systemctl start docker.service

4) install the ca from satellite 6

1. rpm -Uvh http://sat6.lyletech.lab/pub/katello-ca-consumer-latest.noarch.rpm

Actual results:
The docker daemon is restarted, and all running containers are stopped as a part of that

Expected results:
Would not expect the rpm to restart a running service

Additional info:
~~~
rpm -qp --scripts katello-ca-consumer-latest.noarch.rpm

1. restart docker if it is installed and running
   if [ -f /usr/lib/systemd/system/docker.service ]; then
   systemctl status docker >/dev/null && \
   systemctl restart docker >/dev/null 2&>1
   elif [ -f /etc/init.d/docker ]; then
   service docker status >/dev/null && \
   service docker restart >/dev/null 2&>1
   ~~~

Perhaps remove this behavior from the RPM, and we could update the docs telling users they will need to restart the docker service prior to being able to build containers with Satellite?
