Problem

Currently, there is no way to specify a custom MAC address for a container's network interface and the MAC address is auto-generated by the system.

Proposed Solution

Add a --mac-address flag to container run and container create commands:

container run --mac-address AA:BB:CC:DD:EE:FF ubuntu
container create --mac-address AA:BB:CC:DD:EE:FF --name mycontainer ubuntu

The flag would:

• Accept standard MAC address format: XX:XX:XX:XX:XX:XX (with : or - separators)
• Validate the MAC address format before creating the container
• Apply to the first network interface
• Be optional (current auto-generation behavior preserved when not specified)
