End-to-end test doesn't work with docker => Replace "-it" flag in docker run

[gruberma]

I use the "-it" flags, when running flapy.sh run locally, so that the user can kill the process using Ctrl-C:
https://github.com/se2p/FlaPy/blob/master/run_line.sh#L86

However, this causes the end-to-end test to fail with the input device is not a TTY when using docker. For podman it works fine.

=> Remove the "-it" flag, but add some mechanism to make the process killable via Ctr-C

Probably you could just start the container without the "-it" option. Then you have to adjust the docker run command with "docker run --name 'my_custom_name'" to reference the container after you've started it. With "docker exec 'my_custom_name'" you should be able to hop into the container just like in interactive mode, right?

This removes the -it option which causes the TTY error, but nevertheless, you can use the container in interactive mode.
