Our installation guide walks through configuring storage nodes
using the LVM driver. LVM now defaults to thinly provisioned,
which requires thing-provisioning-tools to be installed on the
host. So by default, our instructions will result in failure
when we attempt to perform thin provision operations.
This adds mention of installing the required package for each
platform's instructions to get the necessary tools installed.
It also adds device-mapper-persistent-data to bindep for Red
Hat based platforms to get those thin provisioning tools that
were previously missing for these platforms.
Tools appear to be installed by default on Suse platforms.
