satellite-6.3.0-23.0.el7sat.noarch (snap 31)

I crafted a rhel docker image by installing katello-ca certs on it + installing katello-agent package from dogfood repo (without registering to satellite).

- every docker container built from this image runs the following script:

```
subscription-manager register --org="$ORG" --environment="Library" $AUTH
while [ ! -f /tmp/docker-handle/start ]; do
        echo "waiting"
        sleep 0.1
done
echo "Starting goferd in foreground."
goferd -f
```

there's a semaphore file checking (/tmp/docker-handle/start), allowing me to start multiple containers and make them start gofer at the same time, by touching the file inside the mounted share.

i started up the containers in the following loop:
```
for  i in {1..50};do
    sudo docker run -d -v /dev/log:/dev/log -v /tmp/docker-handle:/tmp/docker-handle -t rplevka-6.3
done
```

after they all started up, all appropriate host records appeared on satellite and there were no more /rhsm requests running, i touched the 'start' file, which made all containers to start the gofer, which created pulp.agent* queues at the same time.

i was verifying everything by watching number of queues:

qpid-stat --ssl-certificate /etc/pki/katello/certs/java-client.crt --ssl-key /etc/pki/katello/private/java-client.key -b "amqps://localhost:5671" -q | grep -c pulp.agent

and also monitoring logs.
