Code Issues Proposed changes

Stop update of volume metadata gracefully if 'os' volume is not on LVM

Browse Source 
To upgrade an OpenStack cluster node with preserved partitions and data
from version 6.0 to version 8.0, changes in disk metadata required. These
changes accommodate the metadata to change of provisioning method from
'cobbler' to 'image'.

To avoid failure if the metadata was already altered by the previous
execution of upgrade-node command, the script update_node_partition_data.py
should stop gracefully if no relevant partitions were found.
