Story #8459

# Problem Statement/Use cases:
* As a user I might have content that I no longer need to serve but I want to keep it in the repo for history purposes. I want to still be able to free up some disk space in such case.
* As a user I have repos that have on_demand download policy and I want to clear out downloaded files for those repos. A repository with on_demand download policy will store artifacts locally after they have been requested, but there really isn't a way to have pulp delete the locally stored files and free disk space if these packages are unlikely to be used again.
# Solution
`pulp/api/v3/repositories/<reclaim-disk-space>/`
Provide a separate endpoint which will accept a list of repo hrefs to reclaim disk space for.
* Artifacts only exclusively to that list of repos will be removed. No new versions will be created or removed because content set will not change.
* a `keeplist` option will contain list of repo_version hrefs which will be excluded from Artifact removal.
* The task will only remove those Artifacts that have a corresponding Remote artifact.
* There, however, will be a `force` flag that will remove Artifacts that have no RA( aka uploaded content). This will **not** be a default behavior.
* The task will trim Artifacts regardless of the download policy. ( Content app would be able to stream artifact if it is locally available otherwise with the help of RA( if available) it would download artifact from the remote source)
