caa88777be Parse metadata stored in zookeeper before checking for equality
After #11325 trailing whitespaces has been removed for data skipping
indicies, and it may be different, if you have multiple skip indices,
and in this case new server will not load such tables, because metadata
will be different.

Fix this by re-parse metadata in zookeeper.

c637d99e07 Volumes and storages refactoring:
1. Moved Volume to separate file
  2. Created IVolume interface and implemented current behaviour in implementation of new interface — VolumeJBOD
  3. Replaced all old volume usages with new VolumeJBOD. Where it is unnecessary to have JBOD — left just IVolume.
  4. Removed old Volume completely
  5. Moved StoragePolicy to separated files
  6. Moved DiskSelector to separated files
  7. Removed DiskSpaceMonitor file
