### Current Behavior

when kinesis-mock fails to start (for whatever reason, e.g. a segfault when running the docker image on qemu virtualization), we only get unhelpful error messages from the proxy trying to connect to the backend:

```

During handling of the above exception, another exception occurred:

```

### Expected Behavior

localstack should gracefully terminate the service proxy, and inform with a log message why kinesis failed to start.

### How are you starting LocalStack?

Custom (please describe below)

### Steps To Reproduce

reproduce by modifying `install_kinesis_mock` to load a bin_file that is not meant to be used for your system.

### Environment

_No response_

### Anything else?
