Add env var shutdown_timeout to kernel to avoid deadlock on node shutdown
When a node is shutting down, application_controller will do
exit(Pid,shutdown) on all application masters, and wait for
{'EXIT',Pid,_}. If, for some reason, the application master does not
terminate then application_controller will hang forever waiting for
this 'EXIT' message.
To overcome this problem, a configurable timer is added to kernel -
the enviroment variable 'shutdown_timeout'. If this variable is set to
a positive integer T, application_controller will do exit(Pid,kill)
after T milli seconds if no 'EXIT' message is received.
