Bug#474747: mdcfg: Avoid sync fresh created arrays

[Andrey Melnikov <temnota@kmv.ru>]

Package: mdcfg
Version: 1.24
Severity: normal

Hello.

Please, add mdadm '--assume-clean' options when creating new arrays in
installer to avoid initial resync. This make huge speedups when creating big
arrays (100 Gb or more).
