Description

In the ansible-core CI, we have a process that creates and publishes many collections in parallel for later testing. This is largely to reduce the time of testing.

While updating the version of galaxy_ng that we test against, we have run into several concurrency issues with repo management in galaxy_ng.

Ultimately I believe they fall into 2 categories:

1. Race conditions removing versions that exceed retain_repo_versions
2. Race conditions creating new repo versions

Key Dependency Versions

galaxy-importer==0.4.10
galaxy-ng==4.7.0
pulp-ansible==0.17.0
pulp-container==2.14.5
pulp-glue==0.19.0
pulpcore==3.23.3

Steps to Reproduce

In short, create something like 50 collections, and publish them all in parallel to a single repository.

Actual Behavior

Various tracebacks. See attached files.

Expected Behavior

No tracebacks, all collections uploaded.
