Stephen Taylor 59b825ae48 [ceph-osd, ceph-client] Weight OSDs as they are added 
Currently OSDs are added by the ceph-osd chart with zero weight
and they get reweighted to proper weights in the ceph-client chart
after all OSDs have been deployed. This causes a problem when a
deployment is partially completed and additional OSDs are added
later. In this case the ceph-client chart has already run and the
new OSDs don't ever get weighted correctly. This change weights
OSDs properly as they are deployed instead. As noted in the
script, the noin flag may be set during the deployment to prevent
rebalancing as OSDs are added if necessary.

Added the ability to set and unset Ceph cluster flags in the
ceph-client chart.
