Add support to CLI fro CTRL-C interruption

[crtahlin]

Is your feature request related to a problem? Please describe.
A user cannot stop a command in CLI with CTRL-C combination, the process just continues.

Describe the solution you'd like
When I press CTRL-C I would like the currently issued command to terminate and the CLI prompt is waiting for me.

Otherwise when executing long tasks, like copying a large folder, i have to wait for it the copy to end, which could be hours or days.
