/bin/bash is not always available in Docker images

[antoine-roux]

Hello and thanks for this useful tool!

Maybe you can make it a bit more flexible by letting the user choose the shell he want use to enter in a container.
Today, you impose /bin/bash as shell:

ctop/cgroup_top.py

Line 835 in 0a241d8

run(-2, ['docker', 'exec', '-it', selected_name, '/bin/bash'], interactive=True)

But it is not installed in every Docker images (by example, in very common Alpine ones)

Have a great day,
Antoine
