Create SDNC
    [Documentation]   Creates an SDNC 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='{...}'
