Fix systemctl problem on SLES in ceilometer setup

There is a problem when enable mongodb service on SLES in ceilometer
install section, which uses `systemctl start mongodb.service`.

systemctl is not installed in SLES SP3 by default, and
mongodb.service is not a valid service too. This patch uses common
commands of `service` and `chkconfig` to do the right job.

Fixes a link to the wrong page for DHCP agent install

A previous patch added a link for further assistance during the
DHCP agent installation section of the Neutron single-flat use-case.
Unfortunately, the document it refers to is the one for the controller
and not the network node as required.

This patch updates the recently merged document to represent the
correct page. The backport will also be rectified before merge.
