features:
- Adds a configuration option ``[deploy]disk_erasure_concurrency`` to
define the target pool size used by Ironic Python Agent ramdisk to
erase disk devices. The number of threads created by IPA to erase
disk devices is the minimum value of target pool size and the number of
disks to be erased. This feature can greatly reduce the operation time
for baremetals with multiple disks. For the backwards compatibility,
the default value is 1.
