Description

Currently, adding multiple file system peers in a fan out fashion which looks something like: fs-local(site-a) -> fs-remote(site-c) when fs-local(site-a) -> fs-remote(site-b) relation already exists is not supported. The mirror daemon would bail out asserting:

https://github.com/ceph/ceph/blob/main/src/tools/cephfs_mirror/FSMirror.cc#L397

Remove this constraint. The real deal is adding tests to fs suite to validate this setup.
