Closes#2065 from mjsax/kafka-4302-simplify-ktablesource
1. Create a new `ClientMetadata` to collapse `Set<String> consumerMemberIds`, `ClientState<TaskId> state`, and `HostInfo hostInfo`.
2. Stop reusing `stateChangelogTopicToTaskIds` and `internalSourceTopicToTaskIds` to access the (sub-)topology's internal repartition and changelog topics for clarity; also use the source topics num.partitions to set the num.partitions for repartition topics, and clarify to NOT have cycles since otherwise the while loop will fail.
3. `ensure-copartition` at the end to modify the number of partitions for repartition topics if necessary to be equal to other co-partition topics.
4. Refactor `ClientState` as well and update the logic of `TaskAssignor` for clarity as well.
5. Change default `clientId` from `applicationId-suffix` to `applicationId-processId` where `processId` is an UUID to avoid conflicts of clientIds that are from different JVMs, and hence conflicts in metrics.
6. Enforce `assignment` partitions to have the same size, and hence 1-1 mapping to `activeTask` taskIds.
7. Remove the `AssignmentSupplier` class by always construct the `partitionsByHostState` before assigning tasks to consumers within a client.
8. Remove all unnecessary member variables in `StreamPartitionAssignor`.
9. Some other minor fixes on unit tests, e.g. remove `test only` functions with java field reflection.

There should be only one cases where these clean-ups have a functional impact: replaced repeated identical logs with a single log for the stale controller epoch case.
The rest should just make the code easier to read and make it a bit less wasteful. I did this exercise because unused variables sometimes mask bugs.

This PR makes a couple of enhancements to the `--describe` option of `ConsumerGroupCommand`:
1. Listing members with no assigned partitions.
2. Showing the member id along with the owner of each partition (owner is supposed to be the logical application id and all members in the same group are supposed to set the same owner).
3. Printing a warning indicating whether ZooKeeper based or new consumer API based information is being reported.
It also adds unit tests to verify the added functionality.
Note: The third request on the corresponding JIRA (listing active offsets for empty groups of new consumers) is not implemented as part of this PR, and has been moved to its own JIRA (KAFKA-3853).
