Forward websocket event subscription requests (#22446) 
For now, only the leader of a cluster can handle subscription requests,
so we forward the connection request otherwise.

We forward using a 307 temporary redirect (the fallback way).
Forwarding a request over gRPC currently only supports a single request
and response, but a websocket connection is long-lived with potentially
many messages back and forth.

We modified the `vault events subscribe` command to honor those
redirects. `wscat` supports them with the `-L` flag.

In the future, we may add a gRPC method to handle forwarding WebSocket
requests, but doing so adds quite a bit of complexity (even over
normal request forwarding) due to the intricate nature of the `http` /
`vault.Core` interactions required. (I initially went down this path.)

I added tests for the forwarding header, and also tested manually.
(Testing with `-dev-three-node` is a little clumsy since it does not
properly support experiments, for some reason.)
