/**
* Adds a new floating disk.
*
* There are three types of disks that can be added - disk image, direct LUN and
* https://wiki.openstack.org/wiki/Cinder[Cinder] disk.
*
* *Adding a new image disk:*
*
* When creating a new floating image <>, the API requires the `storage_domain`, `provisioned_size`
* and `format` attributes.
*
* Note that block storage domains (i.e., storage domains with the <> of iSCSI or
* FCP) don't support the combination of the raw `format` with `sparse=true`, so `sparse=false` must be stated
* explicitly.
*
* To create a new floating image disk with specified `provisioned_size`, `format` and `name` on a storage domain
* with an id `123`, send a request as follows:
*
* [source]
* ----
* POST /ovirt-engine/api/disks
* ----
*
* With a request body as follows:
*
* [source,xml]
* ----
*
*
*
* mydisk
* 1048576
* cow
*
* ----
*
*
* *Adding a new direct LUN disk:*
*
* When adding a new floating direct LUN via the API, there are two flavors that can be used:
*
* . With a `host` element - in this case, the host is used for sanity checks (e.g., that the LUN is visible) and
* to retrieve basic information about the LUN (e.g., size and serial).
* . Without a `host` element - in this case, the operation is a database-only operation, and the storage is never
* accessed.
*
* To create a new floating direct LUN disk with a `host` element with an id `123`, specified `alias`, `type` and
* `logical_unit` with an id `456` (that has the attributes `address`, `port` and `target`),
* send a request as follows:
*
* [source]
* ----
* POST /ovirt-engine/api/disks
* ----
*
* With a request body as follows:

*
*
*

*
* To create a new floating direct LUN disk without using a host, remove the `host` element.
*

*

* raw
*
* ----
*
*
* *Adding a floating disks in order to upload disk snapshots:*
*
* Since version 4.2 of the engine it is possible to upload disks with
* snapshots. This request should be used to create the base image of the
* images chain (The consecutive disk snapshots (images), should be created
* using `disk-attachments` element when creating a snapshot).
*
* The disk has to be created with the same disk identifier and image identifier
* of the uploaded image. I.e. the identifiers should be saved as part of the
* backup process. The image identifier can be also fetched using the
* `qemu-img info` command. For example, if the disk image is stored into
* a file named `b7a4c6c5-443b-47c5-967f-6abc79675e8b/myimage.img`:
*
* [source,shell]
