Description

Caldera needs the SIGINT signal to be properly stopped.
As Docker defaults to the SIGTERM signal, a workaround was, until now, to manually send the SIGINT signal.

This PR makes the Docker image directly set the signal tu use when stopping a related container.

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

Building a new image and invoking docker stop <container-id> instead of docker kill --signal=SIGINT <container-id>.
