This PR ensures that teleport-update removes installations of Teleport that are no longer referenced by its configuration (update.yaml) or linked into /usr/local/bin.
Note that the logic avoids removing partially linked installations that are no longer referenced by configuration. This case could occur if a Teleport binary is removed in newer versions of Teleport, as teleport-update only atomically replaces (and never deletes) symlinks.
The teleport-update binary will be used to enable, disable, and trigger automatic Teleport agent updates. The new auto-updates system manages a local installation of the cluster-specified version of Teleport stored in /var/lib/teleport/versions.
