Conflicts and compiler errors:
* .gitignore: trivial conflicts due to support-metrics-common removal, take
upstream changes while keeping local ones.
* build.gradle: take changes to remove support-metrics-common and resolve
conflicts in the conditional disabling of -Werror for some projects.
* confluent-import-control.xml: file was deleted upstream since it was empty,
but it is still used in ce-kafka. Remove support metrics section.
* suppressions.xml: remove support metrics section.
* Partition.scala: trivial conflict in conflict due to spacing.
* PartitionTest.scala: move SlowLog to LogUtils with an adjusted name and make
it work with tiered storage.
* dependencies.gradle: take upstream changes, remove avro and httpmime.
* settings.gradle: take upstream changes, remove support-metrics-common.
* PartitionMakeFollowerBenchmark: adjust to work with tiered, followed same
approach as UpdateFollowerFetchStateBenchmark.
* KafkaZkClientTest: pass None for topic id parameter in
`zkClient.createTopicAssignment` that only exists in ce-kafka.
* AegisIntegrationTest: adjust testAegisWithoutBrokers to set
DEFAULT_API_TIMEOUT_MS_CONFIG and tweak expected
exception message.
* PlaintextAdminIntegrationTest: adjust expected message in
testElectPreferredLeaders.
