Depends on tower-rs/tower#75. Required for #386 In order for the proxy to use the TLS support metadata from the Destination service correctly, we determined that the code for dynamically changing the labels on an already-bound service should be removed, and any change in metadata should cause an endpoint to be rebound. I've modified the proxy so that we no longer update the labels using `futures-watch` (as a sidenote, we no longer depend on that crate). Metadata update events now cause the `tower-discover::Discover` implementation for `DestinationSet` to re-insert the changed endpoint into the load balancer. Upstream PR tower-rs/tower#75 in tower-balance changes the load balancer to honor duplicate insertions by replacing the old endpoint rather than ignoring them; that change is necessary for the tests to pass on this branch.
