Kill/cancel invocation range/group

[slinkydeveloper]

A lot of these requests when being invoked will start failing because of the invalid string key. Then the user would have to manually kill all ingested invocations

Independently from the context of the PR, this comment here https://github.com/restatedev/restate/pull/815#discussion_r1350016807 makes me wonder whether we should have a way to kill/cancel a range of invocations.

This could be useful in general in many situations where the user deployed a bad service, or many requests were received with wrong payload due to a misconfiguration/bad contract.

This could be a useful admin command, indeed. What is a bit unclear to me is how much control would a user want to have over the range/set (full range/set vs. partial range/set).

This feature can probably be implemented driven by demand from our users.

Same. Perhaps some simple strategies that can be useful for development are "kill all invocations to this service" or even better "to this service instance" (for keyed services).
