Avoid calling into ConfigCommand and TopicCommand from tests that are not related
to these commands. It's better to just invoke the admin APIs.
Change a few cases where we were testing the deprecated --zookeeper flag to testing
the --bootstrap-server flag instead. Unless we're explicitly testing the deprecated code
path, we should be using the non-deprecated flags.
Move testCreateWithUnspecifiedReplicationFactorAndPartitionsWithZkClient from
TopicCommandWithAdminClientTest.scala into TopicCommandWithZKClientTest.scala,
since it makes more sense in the latter.

This patch ensures that `SslEngineFactory` is closed. The default implementation (**DefaultSslEngineFactory**) does not have any releasable object so we didn't notice this issue. However, it would be better to fix this issue for custom engine factories.

Comparing all other test cases, the shouldAllowConcurrentAccesses starts an async producer sending records throughout the test other than just synchronously sent and acked a few records before we start the streams application. Right after the streams app is started, we check that at least one record is sent to the output topic (i.e. completed processing). However since only this test starts the producer async and did not wait for it to complete, it is possible that the async producer gets too longer to produce some records and causing it to fail.
To follow what other tests did, I let this test to first send one round of records synchronously before starting the async producing.
Also encountered some new scala warnings that I fixed along with this PR.

1. Added a recordInternal function to let all other public functions trigger, so that shouldRecord would only be checked once.
2. In Streams, pass along the current wall-clock time inside InternalProcessorContext when process / punctuate which can be passed in to the record function to reduce the calling frequency of SystemTime.milliseconds().

ConfigProvider extends Closeable, but were not closed in the following contexts:
* AbstractConfig
* WorkerConfigTransformer
* Worker
This commit ensures that ConfigProviders are close in the above contexts.
It also adds MockFileConfigProvider.assertClosed()
Gradle executes test classes concurrently, so MockFileConfigProvider
can't simply use a static field to hold its closure state.
Instead use a protocol whereby the MockFileConfigProvider is configured
with some unique ket identifying the test which also used when calling
assertClosed().

After KIP-219, responses are sent immediately and we rely on a combination
of clients and muting of the channel to throttle. The result of this is that
we need to track `apiThrottleTimeMs` as an explicit value instead of
inferring it. On the other hand, we no longer need
`apiRemoteCompleteTimeNanos`.
Extend `BaseQuotaTest` to verify that throttle time in the request channel
metrics are being set. Given the nature of the throttling numbers, the test
is not particularly precise.
I included a few clean-ups:
* Pass KafkaMetric to QuotaViolationException so that the caller doesn't
have to retrieve it from the metrics registry.
* Inline Supplier in SocketServer (use SAM).
* Reduce redundant `time.milliseconds` and `time.nanoseconds`calls.
* Use monotonic clock in ThrottledChannel and simplify `compareTo` method.
* Simplify `TimerTaskList.compareTo`.
* Consolidate the number of places where we update `apiLocalCompleteTimeNanos`
and `responseCompleteTimeNanos`.
* Added `toString` to ByteBufferSend` and `MultiRecordsSend`.
* Restrict access to methods in `QuotaTestClients` to expose only what we need
to.

If a broker contains 8k replicas, we would previously issue 8k ZK calls to retrieve topic
configs when processing the first LeaderAndIsr request. That should translate to 0 after
these changes.

This PR fixes and improves two major issues:
1. When calling KafkaStreams#store we can always get an InvalidStateStoreException, and even waiting for Streams state to become RUNNING is not sufficient (this is also how OptimizedKTableIntegrationTest failed). So I wrapped all the function with a Util wrapper that captures and retries on that exception.
2. While trouble-shooting this issue, I also realized a potential bug in test-util's produceKeyValuesSynchronously, which creates a new producer for each of the record to send in that batch --- i.e. if you are sending N records with a single call, within that call it will create N producers used to send one record each, which is very slow and costly.

Reviewers: Bruno Cadonna <bruno@confluent.io>, A. Sophie Blee-Goldman <sophie@confluent.io>
These two options are essentially incompatible, as caching will do nothing to reduce downstream traffic and writes when it has to allow non-unique keys (skipping records where the value is also the same is a separate issue, see KIP-557). But enabling caching on a store that's configured to retain duplicates is actually more than just ineffective, and currently causes incorrect results.
We should just log a warning and disable caching whenever a store is retaining duplicates to avoid introducing a regression. Maybe when 3.0 comes around we should consider throwing an exception instead to alert the user more aggressively.

This PR updates the algorithm which limits the number of members within a group (`group.max.size`) to fix the following two issues:
1. As described in KAFKA-9885, we found out that multiple members of a group can be evicted if the leader of the consumer offset partition changes before the group is persisted. This happens because the current eviction logic always evict the first member rejoining the group.
2. We also found out that dynamic members, when required to have a known member id, are not always limited. The caveat is that the current logic only considers unknown members and uses the group size, which does not include the so called pending members, to accept or reject a member. In this case, when they rejoins, they are not unknown member anymore and thus could bypass the limit. See `testDynamicMembersJoinGroupWithMaxSizeAndRequiredKnownMember` for the whole scenario.
This PR changes the logic to address the above two issues and extends the tests coverage to cover all the member types.

In this commit we made sure that the auto leader election only happens after the newly starter broker is in the isr.

A broker throws IllegalStateException if the broker epoch in the LeaderAndIsr/UpdateMetadataRequest/StopReplicaRequest is larger than its current broker epoch. However, there is no guarantee that the broker would receive the latest broker epoch before the controller: when the broker registers with ZK, there are few more instructions to process before this broker "knows" about its epoch, while the controller may already get notified and send UPDATE_METADATA request (as an example) with the new epoch. This will result in clients getting stale metadata from this broker.
With this PR, a broker accepts LeaderAndIsr/UpdateMetadataRequest/StopReplicaRequest if the broker epoch is newer than the current epoch.
