KAFKA-1414: Speedup broker startup after hard reset and shutdown
This patch increases speed of both hard reset and shutdown by introducing
`log.recovery.threads` and `log.shutdown.threads` properties, which allows to
perform work required for them in parallel, grained by log directories.
Best performance can be achieved by setting thread count to number of log
directories, provided that they are located on dedicated drives. Although that
option should be used with caution due to the possibility of native JVM out of
memory error.
Patch is compiled of changes proposed by Jay Kreps, Alexey Ozeritskiy,
Dmitry Bugaychenko by Anton Karamanov.
All tests are passing.
