Kopia Maintenance Object Lock support

[kaovilai]

Describe the problem/challenge you have

This tracks investigating or implementation to make object lock supported by kopia

Some notes from
kopia/kopia#1067 (comment)

The quick maintenance needs to run reasonably frequently to ensure good performance - without Kopia will become slower and slower as the number of index files grows. How frequently - it depends on your usage
The full maintenance is only needed to free up disk space when data from old snapshots is no longer needed, if you don’t care about that, you can completely disable it (kopia maintenance set --enable-full false) and/or run manually whenever you feel like it (kopia maintenance run --full)
You can prevent maintenance from running as part of all the other commands by passing undocumented --no-auto-maintenance parameter to every command
To use different set of access keys for maintenance, it’s easiest to create a separate config file (kopia repo connect --config-file /path/to/some-other-file.config b2 --access-key=XX and run maintenance manually by explicitly setting that: kopia --config-file=/path/to/some-other-file.config maintenance run
Snapshot retention is evaluated after each snapshot and this is when old snapshots are marked for deletion (this does not delete actual files but only writes ‘tombstone’ markers for existing snapshots so they don’t show up in the list) . Only full maintenance ultimately gets rid of the contents.
