If deprecated interface methods are inherited, the @Deprication tag should be used (instead on suppressing the deprecation warning).

Metadata may be updated from the background thread, so we need to protect access to SubscriptionState. This patch restructures the metadata handling so that we only check pattern subscriptions in the foreground. Additionally, it improves the following:
1. SubscriptionState is now the source of truth for the topics that will be fetched. We had a lot of messy logic previously to try and keep the the topic set in Metadata consistent with the subscription, so this simplifies the logic.
2. The metadata needs for the producer and consumer are quite different, so it made sense to separate the custom logic into separate extensions of Metadata. For example, only the producer requires topic expiration.
3. We've always had an edge case in which a metadata change with an inflight request may cause us to effectively miss an expected update. This patch implements a separate version inside Metadata which is bumped when the needed topics changes.
4. This patch removes the MetadataListener, which was the cause of https://issues.apache.org/jira/browse/KAFKA-7764.

First PR in series to inline the generic parameters of the following bytes stores:
[x] InMemoryKeyValueStore
[ ] RocksDBWindowStore
[ ] RocksDBSessionStore
[ ] MemoryLRUCache
[ ] MemoryNavigableLRUCache
[ ] (awaiting merge) InMemoryWindowStore
A number of tests took advantage of the generic InMemoryKeyValueStore and had to be reworked somewhat -- this PR covers everything related to the in-memory key-value store.

JUnit 4.13 fixes the issue where `Category` and `Parameterized` annotations
could not be used together. It also deprecates `ExpectedException` and
`assertThat`. Given this, we:
- Replace `ExpectedException` with the newly introduced `assertThrows`.
- Replace `Assert.assertThat` with `MatcherAssert.assertThat`.
- Annotate `AbstractLogCleanerIntegrationTest` with `IntegrationTest` category.

In TopologyTestDriver constructor set non-null topic; and in unit test intentionally turn on caching to verify this case.

- Use Xlint:all with 3 exclusions (filed KAFKA-7613 to remove the exclusions)
- Use the same javac options when compiling tests (seems accidental that
we didn't do this before)
- Replaced several deprecated method calls with non-deprecated ones:
- `KafkaConsumer.poll(long)` and `KafkaConsumer.close(long)`
- `Class.newInstance` and `new Integer/Long` (deprecated since Java 9)
- `scala.Console` (deprecated in Scala 2.11)
- `PartitionData` taking a timestamp (one of them seemingly a bug)
- `JsonMappingException` single parameter constructor
- Fix unnecessary usage of raw types in several places.
- Add @SuppressWarnings for deprecations, unchecked and switch fallthrough in
several places.
- Scala clean-ups (var -> val, ETA expansion warnings, avoid reflective calls)
- Use lambdas to simplify code in a few places
- Add @SafeVarargs, fix varargs usage and remove unnecessary `Utils.mkList` method

Part 1 of the suppression API.
* add the DSL suppress method and config objects
* add the processor, but only in "identity" mode (i.e., it will forward only if the suppression spec says to forward immediately)
* add tests

1) As titled, add a rewriteTopology that 1) sets application id, 2) maybe disable caching, 3) adjust for source KTable. This optimization can hence be applied for both DSL or PAPI generated Topology.
2) Defer the building of globalStateStores in rewriteTopology so that we can also disable caching. But we still need to build the state stores before InternalTopologyBuilder.build() since we should only build global stores once for all threads.
3) Added withCachingDisabled to StoreBuilder, it is a public API change.
4) [Optional] Fixed unit test config setting functionalities, and set the necessary config to shorten the unit test latency (now it reduces from 5min to 3.5min on my laptop).

The wakeup-based strategy caused more problems than it
solved, so we'll instead focus on KIP-266.
Revert commit 2d8049b.
Keep the metrics addition and the new test util.
Also keep the tests for shutdown, although they must be ignored until
poll(Duration) is done in the scope of KIP-266.

Updated the upgrade doc as well since we do not have an overloaded function without the deprecated parameter before. Also renamed the 1.2 release version to 2.0.
Reviewers: Bill Bejeck <bill@confluent.io>, Matthias J. Sax <matthias@confluent.io>
Wakeup consumers during shutdown to break them out of any internally blocking calls.
Semantically, it should be fine to treat a WakeupException as "no work to do", which will then continue the threads' polling loops, leading them to discover that they are supposed to shut down, which they will do gracefully.
The existing tests should be sufficient to verify no regressions.

While TopologyTestDriver works well with stores created from KTable it does not with stores from GlobalKTable.
Moreover, for my testing purposes but I think it can be useful to others, I need to get access to the MockProducer inside TopologyTestDriver.
I have added 4 new tests to TopologyTestDriverTest, two for stores from KTable and two for stores from GlobalKTable.
While I was changing the TopologyTestDriver I've also make it implement java.io.Closeable.
