Geo: Package file replication should adhere to selective sync settings

What does this MR do?

In Geo, an admin may choose to selectively sync some subset of groups or project shards. This setting should affect whether a particular Package is replicated, because Packages are owned by projects.

With this MR, a secondary will no longer try to sync new package files which are excluded by selective sync settings.

Resolves #213889 (closed)
