Björn Zettergren 2462c82c0e New defaults for maxRowsInMemory rowFlushBoundary
To bring consistency to docs and source this commit changes the default
values for maxRowsInMemory and rowFlushBoundary to 75000 after
discussion in PR https://github.com/druid-io/druid/pull/2457.

The previous default was 500000 and it's lower now on the grounds that
it's better for a default to be somewhat less efficient, and work,
than to reach for the stars and possibly result in
"OutOfMemoryError: java heap space" errors.

Add additional verbiage about appropriate middle manager host value.

Nishant 9491e8de3b Remove ServerView from RealtimeIndexTasks and use coordinator http endpoint for handoffs
- fixes #1970
- extracted out segment handoff callbacks in SegmentHandoffNotifier
which is responsible for tracking segment handoffs and doing callbacks
when handoff is complete.
- Coordinator now maintains a view of segments in the cluster, this
will affect the jam heap requirements for the overlord for large
clusters.
realtime index task and nodes now use HTTP end points exposed by the
coordinator to get serverView

Gian Merlino 501dcb43fa Some changes that make it possible to restart tasks on the same hardware.
This is done by killing and respawning the jvms rather than reconnecting to existing
jvms, for a couple reasons. One is that it lets you restore tasks after server reboots
too, and another is that it lets you upgrade all the software on a box at once by just
restarting everything.

The main changes are,

1) Add "canRestore" and "stopGracefully" methods to Tasks that say if a task can
   stop gracefully, and actually do a graceful stop. RealtimeIndexTask is the only
   one that currently implements this.

2) Add "stop" method to TaskRunners that attempts to do an orderly shutdown.
   ThreadPoolTaskRunner- call stopGracefully on restorable tasks, wait for exit
   ForkingTaskRunner- close output stream to restorable tasks, wait for exit
   RemoteTaskRunner- do nothing special, we actually don't want to shutdown

3) Add "restore" method to TaskRunners that attempts to bootstrap tasks from last run.
   Only ForkingTaskRunner does anything here. It maintains a "restore.json" file with
   a list of restorable tasks.

4) Have the CliPeon's ExecutorLifecycle lock the task base directory to avoid a restored
   task and a zombie old task from stomping on each other.
