Improve install guide security content

I improved security content in the installation guide as
follows:

1) Renamed basic environment 'passwords' section to 'security' to
   generalize topic.
2) Generalized existing content.
3) Added content about administrative privilege requirements
   including potential interference with deployment automation
   tools.

Recommend backporting to Icehouse.

<title>Passwords</title>
<para>The various OpenStack services and the required software like the
database and the messaging server have to be password protected. You use
these passwords when configuring a service and then again to access the
service. You have to choose a password while configuring the
service and later remember to use the same password when accessing it.
Optionally, you can generate random passwords with the
<application>pwgen</application> program. Or, to create passwords one at a
time, use the output of this command repeatedly:
<screen><prompt>$</prompt> <userinput>openssl rand -hex 10</userinput></screen>
</para>
<para>This guide uses the convention that
<literal><replaceable>SERVICE_PASS</replaceable></literal> is
the password to access the service <literal>SERVICE</literal> and
<literal><replaceable>SERVICE_DBPASS</replaceable></literal> is
the database password used by the service SERVICE to access the
database.

<para>The complete list of passwords you need to define in this guide are:
<title>Security</title>
<para>OpenStack services support various security methods including
password, policy, and encryption. Additionally, supporting services
including the database server and message broker support at least
password security.</para>
<para>To ease the installation process, this guide only covers password
security where applicable. You can create secure passwords manually,
generate them using a tool such as <application>pwgen</application>, or
by running the following command:</para>
<screen><prompt>$</prompt> <userinput>openssl rand -hex 10</userinput></screen>
<para>For OpenStack services, this guide uses
<replaceable>SERVICE_PASS</replaceable> to reference service account
passwords and <replaceable>SERVICE_DBPASS</replaceable> to reference
database passwords.</para>
<para>The following table provides a list of services that require
passwords and their associated references in the guide:

<para>OpenStack and supporting services require administrative privileges
during installation and operation. In some cases, services perform
modifications to the host that can interfere with deployment automation
tools such as Ansible, Chef, and Puppet. For example, some OpenStack
services add a root wrapper to <literal>sudo</literal> that can interfere
with security policies. See the
<link xlink:href="http://docs.openstack.org/admin-guide-cloud/content/root-wrap-reference.html">Cloud Administrator Guide</link>
for more information. Also, the Networking service assumes default values
for kernel network parameters and modifies firewall rules. To avoid most
issues during your initial installation, we recommend using a stock
deployment of a supported distribution on your hosts. However, if you
choose to automate deployment of your hosts, review the configuration
and policies applied to them before proceeding further.</para>
