container-sync: Sync static links similar to how we sync SLOs

Browse Source 
This allows static symlinks to be synced before their target. Dynamic
symlinks could already be synced even if target object has not been
synced, but static links previously required that target object existed
before it can be PUT. Now, have container_sync middleware plumb in an
override like it does for SLO.

are being synced, then you should follow the instructions for
:ref:`symlink_container_sync_client_config` to be compatible with symlinks.
Be aware that symlinks may be synced before their targets even if they are
in the same container and were created after the target objects. In such
cases, a GET for the symlink will fail with a ``404 Not Found`` error. If
the target has been overwritten, a GET may produce an older version (for
dynamic links) or a ``409 Conflict`` error (for static links).
