Fixed mismatched RemoteConfigSpec with reference.conf
Remove try ... catch constructs around invokations of tell, see #2870
fix the first of the issues: too strict test requirement, see #2950

LARS may execute recurring tasks a little too early on occasion, which
is a direct consequence of it trying to keep them running more regularly
and also allowing them to run at 1/tick rate.
make sure that InterruptExceptions are not swallowed, see #2963

also remove an old work-around in CallingThreadDispatcherModelSpec and
describe the rules for interrupting in the testing docs

fix the first of the issues: too strict test requirement, see #2950
Share same instance of deadLetters between LARP and RARP, see #2983
Generate ChildTerminated from all Terminated in RemoteDeploymentWatcher, see #2983

* The problem is that we do remote deployment to a node that isn't alive and with ordinary
  remoting that is not detected at all, as we know. With cluster this was taken care of by
  a later AddressTerminated and ChildTerminated generated by RemoteDeploymentWatcher. With
  the new RemoteDeadLetters the additional watch triggers an immediate Terminate which is
  captured by RemoteDeploymentWatcher but not acted upon since it's not an addressTerminated.
  RemoteDeploymentWatcher unwatch and will therefor not act on later AddressTerminated.
* The long term solution is to have reliable system messages and remote supervision without
  explicit watch, so that we know that the remote deployment fails.
* This short term solution is to let RemoteDeploymentWatcher always generate ChildTerminated,
  also for non-addressTerminated.
* It's possibly racy since ChildTerminated is not idempotent.
Send ChildTerminated before Terminated when AddressTerminated, see #2983

* Replaces the previous half-baked removeChildWhenToAddressTerminated

Remove try ... catch constructs around invokations of tell, see #2870
Remove work-around for sending to broken connections, see #2909

* Previous work-around was introduced because Netty blocks when sending
to broken connections. This is supposed to be solved by the non-blocking
new remoting.
* Removed HeartbeatSender and CoreSender in cluster
* Added tests to verify that broken connections don't disturb live connection
