Fix Kafka Partition Count

[dweinshenker]

What

• Changes Get/List operation responses to include partitions instead of partition_count which is used for Create/Update operations

Why

The API response from Get/List includes 1 or many topics with partitions in the response rather than partition_count. partition_count is used when creating the topic, but the response from the API should include the list of partitions that are created.

https://docs.digitalocean.com/reference/api/api-reference/#operation/databases_get_kafka_topic

An example response from the API is included below:

{
    "topic": {
        "name": "test-topic-1",
        "partitions": [
            {
                "size": 4096,
                "id": 0,

            },
            {
