Setting tag NodeManager-2.0-9
fix for 64bits nodes: add newline to the personality files that instruct util-vserver to create 32bits slivers
basic/partial support from reservable nodes through the 'reservation plugin' (not fully working yet)
plugins can set 'persistent_data' to receive the latests know GetSlivers in case the connection is down
cleanup: moved runtime files in /var/lib/nodemanager, and logs as /var/log/nodemanager* (see specfile)
cleanup: some modules renamed (e.g. nm.py becomes nodemanager.py)
cleanup: nodemanger now is a class; however plugins are still dumb modules
cleanup: does not depend on obsolete Set
