Feature: add acceptance test to ensure connectors can be opened and immediately closed

[alarbada]

Feature description

When developing the kinesis connector I got the following error:

  acceptance_test.go:221: err: error deregistering stream consumer arn:aws:kinesis:us-east-1:000000000000:stream/acceptance_2603d625/consumer/conduit-connector-kinesis-source-01HYBHT28ZYD0F7NJHGQRZFRZA:1716223323: operation error Kinesis: DeregisterStreamConsumer, https response error StatusCode: 400, RequestID: 04399833-3065-431e-b7e6-e9914384d65b, api error ResourceInUseException: Consumer None is not in an ACTIVE state

Kinesis doesn't allow deregistering a consumer that is not ready. While this situation is unlikely, the connector should be able to be opened and immediately closed. Testing for that would have prevented this error.

The acceptance tests already test for open - reading / writing - teardown, but not for open - teardown.
