A user with unbalanced system (e.g., some OSDs use a partition which
resides on a device along-side OS partition) may want to have a
fine-grained control on the overall load of specific OSD. While osd
weight affects write-load, primary-affinity affects read-load.
This patch allow user to define osd's primary-affinity (similar to
'DeviceClass' and 'InitialWeight'), which is sent to the osd (via mon)
as part of deployment sequence, using 'ceph osd primary-affinity' command.
Valid values are within the range [0.0, 1.0). If not set, default value
is 1.
