Refactoring of code:
1) new snapshot module with code vss, lvm and part of backup.py - create_snapshot and remove_snapshot This module should contain all code related shadow, vss and any new snapshots. 2) new openstack module with code from osclient, restore and backup (BackupOS) This module should contain code related to cinder/nova backups 3) new utils module with code from utils, win_utils, bandwidth, config, exec_cmd, validator, streaming This module should containd code related to anything that cannot be extracted to its own module 4) new test modules - snapshot, utils, openstack and apiclient. Test scheduler daemon is now located in scheduler module. 5) Backup.py is deleted and code placed to openstack.backup (BackupOS) and to job.BackupJob Change-Id: I46194b40b3a65c15b6095cfb7388dcfd30d95997changes/16/288416/9
