RPC: PoolService::PrepareLeavePool
This uses git repack
to create a stand-alone packfile in a repository that we want to take out of a pool. This will be relatively slow. It needs to be finalized with PoolService::UnlinkRepositoryFromPool.
Also see worked example in https://gitlab.com/gitlab-org/gitaly/blob/jv-explore-dedup/test-dedup.
