In tccsh, parameters for `stc_create`, `stc_config`, and `stc_perform` can have value lists. These are specified as: `param="value1 value2 value3"`. It was not previously possible to specify a parameter with a list of values.
The `create()`, `createx()`, `config()`, and `perform()` methods of StcHttp can optionally take parameters as kwargs. This allows parameters to be passed as items in a dictionary, as keyword arguments, or both.
