+Create SDNC
+ [Documentation] Register an SDN Controller in OSM.
+ ... The optional parameters (such as 'switch_dpid' or 'ip-address') are given to this function in name=value format. These parameters will be appended to the 'osm sdnc-create' command with the next syntax: --param_name=param_value
+ ... Returns the ID of the created SDNC Target.
+ ... Example of execution:
+ ... \${sdnc_id}= Create SDNC \${sdnc_name} \${sdnc_user} \${sdnc_password} \${sdnc_url} \${sdnc_type} switch_dpid='{...}'
