Josh Durgin 930eae214c OSDMonitor: get stripe_width via stripe_unit in ec profile ... With bluestore, making the smallest write match min_alloc_size avoids write amplification. With EC pools this is the stripe unit, or stripe_width / num_data_chunks. Rather than requiring people to divide by k to get the smallest ec write, allow it to be specified directly via stripe_unit. Store it in the ec profile so changing a monitor config option isn't necessary to set it. This is particularly important for ec overwrites since they allow random i/o which should match bluestore's checksum granularity (aka min_alloc_size).
