gojomo 0b577c1245 [HER-1860] H3: Remove dependence on GC/finalization/PhantomReference magic in used ObjectIdentityCache implementation ...

* IdentityCacheable
    new interface required of objects stored in ObjectIdentityCaches
* IdentityCacheableWrapper
    wrapper for storing arbitrary objects in ObjectIdentityCaches
* ObjectIdentityCache
    keys now always Strings
    values now always IdentityCacheables
    new dirtyKey() method to ensure a key is persisted
* ObjectIdentityBdbCache, ObjectIdentityMemCache
    update for new ObjectIdentityCache shape; still using legacy GC magic
* ObjectIdentityBdbManualCache
    alternate implementation relying on dirtying to ensure persistence
    use Guava library MapMaker for soft memMap; capped dirtyMap
* BdbModule
    use ObjectIdentityBdbManualCache by default
    up expectedConcurrency default to 64
* BdbModuleTest, ObjectIdentityBdbCacheTest, ObjectIdentityBdbManualCacheTest
    update, add tests
* Frontier
    FrontierGroup as IdentityCacheable
* AbstractFrontier, WorkQueueFrontier, BdbFrontier
    touchup queue/group accessors
    make queue instances dirty whenever mutated 
* WorkQueue, CrawlHost, CrawlServer
    IdentityCacheable support; appropriate makeDirty()s
* ServerCache, DefaultServerCache
    update for new ObjectIdentityCache shape
