##### SUMMARY
<!-- Explain the problem/feature briefly -->
When a user sets up recurring volume snapshot, if the number of snapshots to
keep (example 3) is less than the snapshot.delta.max (example 7), it creates a
chain of 7, but the cloud_usage table shows as if the first 4 snapshots were
destroyed, while the physically continue to exist and take up secondary storage
space. This is creating artifically low secondary storage usage and creates
billing challenges as well as shows incorrect information to users.
NOTE - this used to work correctly in 4.17 (I upgraded from 4.17 to 4.19
recently - I skipped 4.18).
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal
test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
<!-- Paste example playbooks or commands between quotes below -->
~~~
Set up global config snapshot.delta.max = 7.
Setup a Volume recurring snapshot with Keep = 3 (I only used the Daily
option).
Observe the cloud_usage table. On Fourth day, you will notice that there are
4 physical snapshots present in secondary storage due to chaining, but the
usage for 4th day only shows as if 3 were in use.

##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
The entire snapshot chain should be shown in the cloud_usage for each date
regardless of the number of snapshots to keep.
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
Only the last 3 snapshots are shown as existing ones.
