Description of problem:
When we have repository on local machine and custom repo created on it, after deleting some packages from local repo, regenerating it and syncing custom repo from katello side, still it lists that packages in "package list --repo --org --product" CLI command.

How reproducible:
always

Steps to Reproduce:
1. Create local repo in "/var/www/html/testrepo" directory. For this we need to install "createrepo", download some RPMs for example from zoo repo, and execute "createrepo /var/www/html/testrepo"
2. Create custom provider/product/repo and link local repo url there "http://localhost/testrepo". Sync repo.
3. Try to download new RPMs and remove some RPMs from local repo. Again execute "createrepo /var/www/html/testrepo" command. Sync custom repo in katello side.
4. Try to list packages from custom repo: "package list --repo $repo --org $org --product $prod". You will see that removes RPMs are still there.

Actual results:
deleted RPMs are still in repo package list

Expected results:
they should be removed

Additional info:
in repodata ".....filelists.xml.gz" file removed RPMs are not included after ""createrepo /var/www/html/testrepo"
