  1. feat: Add SHOW TOPICS EXTENDED 

    Fixes confluentinc#1268

BREAKING CHANGE: "SHOW TOPICS" no longer includes the "Consumers" and
"ConsumerGroups" columns. You can use "SHOW TOPICS EXTENDED" to get the
output previous emitted from "SHOW TOPICS". See below for examples.

This change splits "SHOW TOPICS" into two commands:

1. "SHOW TOPICS EXTENDED", which shows what was previously shown by
"SHOW TOPICS". Sample output:

```
    ksql> show topics extended;

     Kafka Topic                                                                                   | Partitions | Partition Replicas | Consumers | ConsumerGroups
    --------------------------------------------------------------------------------------------------------------------------------------------------------------
     _confluent-command                                                                            | 1          | 1                  | 1         | 1
     _confluent-controlcenter-5-3-0-1-actual-group-consumption-rekey                               | 1          | 1                  | 1         | 1
```

2. "SHOW TOPICS", which now no longer queries consumer groups and their
active consumers. Sample output:

```
    ksql> show topics;

     Kafka Topic                                                                                   | Partitions | Partition Replicas
    ---------------------------------------------------------------------------------------------------------------------------------
     _confluent-command                                                                            | 1          | 1
     _confluent-controlcenter-5-3-0-1-actual-group-consumption-rekey                               | 1          | 1
```

This changeset primarily involved renaming KafkaTopicXXX classes to
KafkaTopicXXXExtended and then trimming out the consumer group info from
the original KafkaTopicXXX classes.
