Select the default Disk allocation strategy to be used when allocating disks within this Disk Pool.

The allocation strategy may also be provided in the Pipeline code, thus will override the one defined in the global config.

Note: Some Disk allocation strategies may require additional information to be provided. For example, if you choose the fastest read/write speed strategy, then you must provide, for each disk, its read/write speeds. These values should be set in the Disk Information section, for each Disk entry from the Jenkins global config.
