see https://github.com/linkerd/linkerd2/issues/8733 and
https://github.com/linkerd/linkerd2-proxy/pull/3504 for more
information.

see also linkerd/drain-rs#36 for a related pull request that
updated `drain`'s `tower` dependency. see #3715 (2f97549a) for a related
pull request that made `tower` a workspace dependency.

see #3456 (c740b6d8), #3466 (ca50d6bb), #3473 (b87455a9), and #3701
(cf4ef39), for some other previous pr's that moved dependencies to be
