Extend the ability to skip disks to RAID devices
This allows users to specify the volume name of
a logical device in the skip list which is then not cleaned
or created again during the create/apply configuration phase
The volume name can be specified in target raid config provided

Certain filesystems are sometimes used in specialty computing
environments where a shared storage infrastructure or fabric exists.
These filesystems allow for multi-host shared concurrent read/write
access to the underlying block device by *not* locking the entire
device for exclusive use. Generally ranges of the disk are reserved
for each interacting node to write to, and locking schemes are used
to prevent collissions.
These filesystems are common for use cases where high availability
is required or ability for individual computers to collaborate on a
given workload is critical, such as a group of hypervisors supporting
virtual machines because it can allow for nearly seamless transfer
of workload from one machine to another.
Similar technologies are also used for cluster quorum and cluster
durable state sharing, however that is not specifically considered
in scope.
Where things get difficult is becuase the entire device is not
exclusively locked with the storage fabrics, and in some cases locking
is handled by a Distributed Lock Manager on the network, or via special
sector interactions amongst the cluster members which understand
and support the filesystem.
As a reult of this IO/Interaction model, an Ironic-Python-Agent
performing cleaning can effectively destroy the cluster just by
attempting to clean storage which it percieves as attached locally.
This is not IPA's fault, often this case occurs when a Storage
Administrator forgot to update LUN masking or volume settings on
a SAN as it relates to an individual host in the overall
computing environment. The net result of one node cleaning the
shared volume may include restoration from snapshot, backup
storage, or may ultimately cause permenant data loss, depending
on the environment and the usage of that environment.
Included in this patch:
- IBM GPFS - Can be used on a shared block device... apparently according
to IBM's documentation. The standard use of GPFS is more Ceph
like in design... however GPFS is also a specially licensed
commercial offering, so it is a red flag if this is
encountered, and should be investigated by the environment's
systems operator.
- Red Hat GFS2 - Is used with shared common block devices in clusters.
- VMware VMFS - Is used with shared SAN block devices, as well as
local block devices. With shared block devices,
ranges of the disk are locked instead of the whole
disk, and the ranges are mapped to virtual machine
disk interfaces.
It is unknown, due to lack of information, if this
will detect and prevent erasure of VMFS logical
extent volumes.

IPA standalone mode is a developer-only option, and if enabled
accidentally on a production agent could cause undesired behavior.
Developers who need this behavior should build a purpose-built agent,
with standalone hardcoded to True in cmd/agent.py.

It'd allow for example custom ansible playbooks to use UUIDs of the
introspected node's disks. In future it might also enable agent
to use UUID (or by_path value) to refer to a device instead of
name, as it happens currently.

Switch to openstackdocstheme 2.2.1 and reno 3.1.0 versions. Using
these versions will allow especially:
* Linking from HTML to PDF document
* Allow parallel building of documents
* Fix some rendering problems
Update Sphinx version as well.
Set openstackdocs_pdf_link to link to PDF file. Note that
the link to the published document only works on docs.openstack.org
where the PDF file is placed in the top-level html directory. The
site-preview places the PDF in a pdf directory.
Disable openstackdocs_auto_name to use 'project' variable as name.
Change pygments_style to 'native' since old theme version always used
'native' and the theme now respects the setting and using 'sphinx' can
lead to some strange rendering.
openstackdocstheme renames some variables, so follow the renames
before the next release removes them. A couple of variables are also
not needed anymore, remove them.
This repo uses storyboard, configure the proper variables.
