Rename test directories in infix_containers/ to remove the redundant 'container_' prefix since they already live under infix_containers/: container_basic -> basic container_bridge -> bridge container_enabled -> enabled container_environment -> environment container_firewall_basic -> firewall_basic container_host_commands -> host_commands container_phys -> phys container_veth -> veth container_volume -> volume Also update references in all.yaml and Readme.adoc files.

r"""Host Command Execution from Container
|
|
|
|
This test verifies that a container running on Infix can execute commands
|
|
that affect the host system. Specifically, it confirms that the container
|
|
can change the hostname of the host.
