We should see the ECMP group updated with one bucket removed

Some deployed bcm and bf binaries are without the SFP fix. This causes crashed when cables are removed.

We should make sure all binaries are up-to-date.

As of now, path restoration is not supported because the routing app component doesn't compute e2e paths when routing across spines. Packets destinated to other leaves are hashed to all spines, ignoring wether a spine as a link to the destination leaf or not.
