Prior to this commit, the SSL file hot reloading feature would
create file watchers for all configured locations and would resolve
symbolic links if they're found as registrations.
This arrangement would work for typical Let's Encrypt setups, but
would not get notified of consecutive changes for k8s setups.
Kubernetes uses a mix of symlinks and atomic file moves to update
secrets.
This commit not only tracks changes to symlinks targets, but also
to the original symlink.
