Code Issues Proposed changes

Manila install guide: Fix wrong instructions 

Previously only the DHSS=True mode was documented
in post install steps. The assumption that the generic driver
was being configured existed in other places as well.

* add DHSS=False documentation as necessary with the
   LVM driver.
* correct assumptions in other places to clarify usage
   of appropriate share driver modes.

Creating shares with Shared File Systems Option 2 (DHSS = True)
---------------------------------------------------------------
Before being able to create a share, manila with the generic driver and
the DHSS (``driver_handles_share_servers``) mode enabled requires the
definition of at least an image, a network and a share-network for being
used to create a share server. For that `back end` configuration, the share
server is an instance where NFS shares are served.
.. note::
This configuration automatically creates a cinder volume for every share.
The cinder volumes are attached to share servers according to the
definition of a share network.

#. Create a manila share server image in the Image service. You may skip this
step and use any existing image. However, for mounting a share, the service
image must contain the NFS packages as appropriate for the operating system.
Whatever image you choose to be the service image, be sure to set the
configuration values ``service_image_name``, ``service_instance_flavor_id``,
``service_instance_user`` and ``service_instance_password`` in
``manila.conf``.
.. note::
Any changes made to ``manila.conf`` while the ``manila-share`` service
is running will require a restart of the service to be effective.
.. note::
As an alternative to specifying a plain-text
``service_instance_password`` in your configuration, a key-pair may be
specified with options ``path_to_public_key`` and
``path_to_private_key`` to configure and allow password-less SSH access
between the `share node` and the share server/s created.

The storage protocol used and referenced in this guide is ``NFS``. As

For the ``generic`` back end, networking service configuration requires
the capability of networks being attached to a public router in order to
create share networks. If using this back end, ensure that Compute,
Networking and Block storage services are properly working before you
proceed. For networking service, ensure that option 2 (deploying the
networking service with support for self-service networks) is properly
configured.

of OpenStack packages, Network Time Protocol, database engine and
message queue has been completed as per the instructions in the `OpenStack
Installation Tutorial. <http://docs.openstack.org/#install-guides>`_. The
`Identity Service` (`keystone`) has to be pre-configured with suggested
client environment scripts.

Creating shared file systems
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Creating and using shared file systems
======================================
Before being able to create a share, manila with the generic driver and
the DHSS mode enabled requires the definition of at least an image,
a network and a share-network for being used to create a share server.
For that `back end` configuration, the share server is an instance where
NFS/CIFS shares are served.
Depending on the option chosen while installing the share node (Option with
share server management and one without); the steps to create and use your
shared file systems will vary. When the Shared File Systems service handles
the creation and management of share servers, you would need to specify the
``share network`` with the request to create a share. Either modes will vary
in their respective share type definition. When using the driver mode with
automatic handling of share servers, a service image is needed as specified
in your configuration. The instructions below enumerate the steps for both
driver modes. Follow what is appropriate for your installation.
.. note::
This configuration automatically creates a cinder volume for every share.
The cinder volumes are attached to share servers according to the
definition of a share network.

#. Configure user access to the new share before attempting to mount it via
the network:
.. important ::
The image used for launching an instance and mounting a share must have
the NFS packages provided by the distro. Example: The cirros image
created at the image service section is not enough.
.. important ::
Use an instance that is connected to the private network used to create
the share-network.
.. code-block:: console
$ manila access-allow demo-share1 ip INSTANCE_PRIVATE_NETWORK_IP
Mount the share from an instance
--------------------------------
#. Create a folder where the mount will be placed:
.. code-block:: console
$ mkdir ~/test_folder
#. Mount the NFS share in the instance using the export location of the share:
.. code-block:: console
$ mount -v 10.254.0.6:/shares/share-0bfd69a1-27f0-4ef5-af17-7cd50bce6550 ~/test_folder
