Documentation bugs on initial commit

[Alex Kavanagh]

Initial docs issues found in the document:

Some review comments on 'install-openstack.rst':

In the "Deploy OpenStack" section under "Ceph OSD"

odd wording "Change or ignore this to match your own configuration. "
Under "Swift proxy":

It mentions the "uuid command used previously". However, this is never mentioned anywhere else in the documentation.

On the "install-openstack-bundle.html" page:

The links are missing for:

Install the openstack bundle
For our project, [download the OpenStack][downloadbundle] and deploy OpenStack using the above command.

Also something is probably needed to be said about customising the bundle for the hardware available; e.g. placement of services, etc. according to hardware, convergence, etc.

In "config-openstack.html":

In the 'define and external network' section:

typo: " called Pub_Net that will use a subnet with within the range of "
The Note should be an rst note: !!! Note: OpenStack has deprecated the use of the neutron command for network configuration, migrating most of its functionality into the Python OpenStack client. Version 2.4.0 or later of this client is needed for the subnet create command.

    Fix some documentation issues

    - Fixed odd wording in install-openstack.rst.
    - Fixed up uuid command usage.
    - Added missing links and added note about editting bundles.
    - Fixed up the note to be an RST note rather than just regular
