NoopRequest should be the cheapest raft command to apply (since it's deterministically rejected below raft, i.e. only writes the LeaseAppliedState update) but accidentally it wasn't marked as a trivial ("batchable") command. We think this wildly inflates the cost of applying such a command, as seen in https://github.com/cockroachlabs/support/issues/2287.

We should fix this.
