The class swift::storage::disk now has 2 new parameters called
manage_partition and manage_filesystem. The swift::storage::xfs now has
a new parameter manage_filesystem. Both have a value of true by default.
These new options may be used to skip running parted and xfs_admin once
the storage disks are setup. The goal is to avoid the kernel to flush
the HDD buffer, which can seriously increase the load and IO wait on a
(busy) production server. These parameters should be left to true when
setting-up a new server, or when changing a disk, and can be set to false
otherwise, or always set to false if the formating is done outside of
puppet.
