Subject: [PATCH 553/584] cluster/ec: Change self-heal-window-size to 4MiB by
 default (#2071)

The current block size used for self-heal by default is 128 KiB. This
requires a significant amount of management requests for a very small
portion of data healed.

With this patch the block size is increased to 4 MiB. For a standard
EC volume configuration of 4+2, this means that each healed block of
a file will update 1 MiB on each brick.
