Create VIM Target
    [Documentation]   Register a VIM account in OSM and return the id.
    ...                 The optional parameters (such as 'config' or 'sdn_controller') are given to this function in name=value format. These parameters will be appended to the 'osm vim-create' command with the next syntax: --param_name=param_value
    ...                 Return the ID of the created VIM Target.
    ...                 Example of execution:
