Controlled shutdown safety check

Adds a topic availability safety check to the controlled shutdown protocol.

New broker config properties include:

• controlled.shutdown.safety.check.enable: Enable this safety check for any ControlledShutdownRequest handled by the controller.
• controlled.shutdown.safety.check.redundancy.factor: Additional replicas above min.insync.replicas that are required for any topic-partition to allow shutdown of a broker. Default is 2, so if a topic has min.insync.replicas=2, then the ISR must have 4 replicas to allow shutdown.

Also included in this release is a fix from upstream (10b0757) for KAFKA-10794, Replica leader election is too slow in the case of too many partitions.

Move Logging to companion classes

[LI-HOTFIX] Move the logging trait to a companion object. (#104)

TICKET = KAFKA-10877
LI_DESCRIPTION = When Log4j2 is used in JDK11 it uses a different class from JDK 8 to determine where the logger was instantiated (which class instantiated the logger). The StackWalker class is used to do this. The StackWaker turns out to be very slow which causes low RHIPR on the brokers. This cpu cost occurs even if a log message is not emitted as the logger needs to perform this initialization even to find out if a log message needs to be emitted. If loggers are not initialized frequently then this cost is low when amortized over runtime of the broker. This patch moves the Logging trait from some classes into companion objects. This initializes the logger only once for each of these classes instead of every time a class is instantiated. The larger patch of doing this move to every class which currently mixes in Logger is more complicated and will be attempted in open source.
