Cloudserver will now apply the clean read filter to all apis and deployments (internal and external cloudserver) : It will not see objects whose data is located on a different location.

One exemption : the get backbeat metadata api, which queries objects with specific versions. If it applied the clean read filter, we would end up with the data mover getting noSuchKey for objects where it's trying to move their locations.

The exemption is safe to do even though the api is used for by other components than the data mover, because get metadata queries a specific versionID, and that version ID is discovered through a listing, but the listing api applies the clean read filters anyways so there is no ris of querying non localized objects.

Issue: CLDSRV-957

Looks good, to be confirmed/tested.

Maybe should wait until the prettier PR is merged, to avoid conflict?

should this be the default in MetadataWrapper (in arsenal) instead?

I think its weird to have arsenal use true because we still need cloudserver to pass the config location constraints which will become some kind of flag itself
