Keepalived Connections Reset after reloading the configuration (HUP Signal)

[zakirenish]

Having similar issue. Clients connections getting closed on reload. 

Maxim, would you point me to a code location where I can make server wait
for `worker_shutdown_timeout` before terminating the conenction? 
either through `ngx_set_shutdown_timer(cycle);` or sleep on
`ccf->shutdown_timeout`? 

I am looking through `ngx_process_cycle.c` where the QUIT signal sent on the
channel. But having hard time figuring out what I should change.

I would really appreciate it!
