Chronicle Map 3.11.0

[Roman Leventov]

Chronicle Map 3.11.0 brings improvements to stability and manageability of Chronicle Map, especially in use cases when ChronicleMaps are small and/or short-living, and/or there are many of them in the JVM.

Highlights:

 - Shutdown hook prevents persisted memory corruption on System.exit() or external `kill -SIGINT`.

 - Fix memory leak, reported twice lately

 - Manageability: ChronicleMap.offHeapMemoryUsed(), and .toIdentityString()

 - Default serializers don't allocate direct memory now
