dm: acrn-tool: Add new parameter for acrnctl add 

This patch adds the "-C" parameter handing in acrnctl. The "-C"
parameter be introduced for acrn-dm QoS feature. By current acrnctl
implementation, it will dry run the launch_uos.sh script to obtain the
VM name which defined during script execution.
The patch will strip "-C" parameter during the script dry run to avoid
create unexpected container, and add the "-C" parameter to the arguments
file after the script dry run.
