/**
* 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.
*
* 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:
*
* [source,xml]
* ----
*
* mylun
*
* iscsi
*
*
* 10.35.10.20
* 3260
* iqn.2017-01.com.myhost:444
*
*
*
*
* ----
*
* To create a new floating direct LUN disk without using a host, remove the `host` element.
*
*
* *Adding a new Cinder disk:*
*
* To create a new floating Cinder disk, send a request as follows:
*
* [source]
* ----
* POST /ovirt-engine/api/disks
* ----
*
* With a request body as follows:
*
* [source,xml]
