[svor]

Description

We should have a functionality to stop/cancel running tasks.
For example if some task executes a process sleep infinity there are should be a way to cancel this process without using a terminal.

We run che tasks using machine exec, machine exec doesn't have ability to stop process.
So, first of all we need to provide ability to stop process on machine exec side and next - provide UI for stopping task.

Thanks Roman. Is that something you can handle?

Changes for https://github.com/eclipse/che-machine-exec are required, so - unfortunately - no.
We discussed about that with @AndrienkoAleksandr and the main problem is to get id of a running process, as far as I understand.

By the way, now we can Ctrl-c to stop a running task as tasks are interactive.
But would be nicer to Ctrl-c when you close the tab right ?

I implemented stopping che tasks by sending ctrl+c to corresponding terminal widget, but unfortunately, I faced with the issue #14887
