Killing the parent process through ^C does not kill the worker processes

[tusharr]

When I try to kill the parent hydra process using Ctrl + C, the workers continue to do their work.

It would be nice if the workers are also killed when the parent dies.

Hydra closes the connection to the worker on a CTRL+C. When the worker detects the closed connection (when it finished the current job) it will exit. Sometimes there is a brief delay, based on how long the jobs take.
