Add ip and mac valid check functionality

Add function check_input_para in /deploy/launch.sh to check
whether there is invalid address in DHA and NETWORK file after
function process_input_para is called.

Check_input_para is defined in /deploy/deploy_parameter.sh and
calls check_valid.py in /util. Exit installation when invalid
address or format error is found.
