Expand Snapshot Size Information

[onenhansen]

Description
Currently each individual snapshot does not have it's size directly monitored, and it can be useful to have the information of how much space each individual snapshot takes up.

Use case
this information could be useful when deciding when to revert to snapshots by indicating the amount of data that has changed.

Interface Changes
An extra column or data display for size under both snapshot displays.

Additional Context
This data should be able to be gathered when the snapshot has been taken rather than being monitored with each monitoring cycle to ensure there is not a large impact on systems with many snapshots.

Progress Status

• Code committed
• Testing - QA
• Documentation (Release notes - resolved issues, compatibility, known issues)
