[HDDS-4180] Schema Version field in Container metadata file should be backward compatible during read/write.

• Type: Sub-task
• Status: Resolved
• Priority: Major
• Resolution: Not A Problem
• Target Version/s: 1.2.0
• Release Note: Decided that downgrade will not be supported until the 1.1.0 to 1.2.0 upgrade, during which users can downgrade to 1.1.0. This means this will not be a problem, since it only occurs downgrading to 1.0.0.
