Clay Gerrard 3824ff3df7 Add Storage Policy support to Object Server ...

Objects now have a storage policy index associated with them as well;
this is determined by their filesystem path. Like before, objects in
policy 0 are in /srv/node/$disk/objects; this provides compatibility
on upgrade. (Recall that policy 0 is given to all existing data when a
cluster is upgraded.) Objects in policy 1 are in
/srv/node/$disk/objects-1, objects in policy 2 are in
/srv/node/$disk/objects-2, and so on.

 * 'quarantined' dir already created 'objects' subdir so now there
   will also be objects-N created at the same level

This commit does not address replicators, auditors, or updaters except
where method signatures changed. They'll still work if your cluster
has only one storage policy, though.
