@devmadhuu @xBis7 can you'll please take a look?

IMHO, displaying the number of missing containers would be much more useful than the number of deleted containers. Does it make more sense to see how many of the existing containers have gone missing or are unhealthy? Or how many data you didn't need and eventually deleted?

@xBis7
Missing Containers functionality is already implemented in overview page.

@xBis7 Thanks for your review, I think Recon displays the missing containers and unhealthy containers under "Containers" tab. This PR is mainly focussed to show count on Overview page.

@devmadhuu I know and also there is the number of containers next to each tab header (missing, under-replicated, ...). Why would the user want to see the number of deleted containers?

@xBis7 as far as i know , this count of deleted containers was done based on multiple issues being faced while debugging customer issues, so needed this info to correlate with information in rocks db. Mainly targeted for admin users not for direct customers.

@devmadhuu Thanks for the info. Based on that, this PR looks good.

CI failure seems unrelated.
