TC: Induce holes in layout by remove brick force then fix-layout
Objective: When induced holes in the layout by remove brick force, fix-layout start should fix the layout without any holes or overlaps. Change-Id: Ie4c47fff11957784044e717c644743263812a0e4 Signed-off-by: Prasad Desala <tdesala@redhat.com>
