    Add thin provisioning package to install guide

    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.
