changed the way it checks package and service status to make it runs on
all language
Update oo_deployment_guide_comprehensive.adoc

yum install -y mongodb-server didn't actually install the mongodb package as a dependency, and I had to install it separately. Therefore I have added mongodb to the yum install line to save time/troubleshooting for others.
<docs> Added libmongodb to the yum install command for MongoDB

Some rest-domains.feature tests rely on DEFAULT_MAX_DOMAINS = 1

Update the user's max domain value instead of relying on the broker.conf
default value.

Bug 1026367 - starting openshift-iptables-port-proxy after the network is up
Bug 1026367 - Improving oo-admin-ctl-iptables-port-proxy "UI"

Previously the restart, reload, stop and status commands were noop.  This can
be confusing for admins.

Now:

stop: flushes the rhc-app-comm chain
restart: calls stop then start
reload: calls start
status: removed

The motivation for this is the following:

1 Admin sees something weird with the rhc-app-comm chain not working as expected
2 Admin runs `for s in 'iptables network openshift-iptables-port-proxy'; do server $s restart'
3 Admin notices rhc-app-comm is still empty and is really confused

In this case the event that trigged #1 is that net.ipv4.conf.all.route_localnet
wasn't set in /etc/sysctl.conf.
