KIP-875 introduced a new target state for connectors: STOPPED. This state differs from PAUSED in that it completely shuts down all tasks for the connector, instead of leaving them active but on standby.

It's also a requirement for connectors to be in that state before their offsets can be reset or altered.

Since support for this new state was added in Kafka 3.5, we can and should add support for it in kcctl.
