Add function objects to completions

[llan-ml]

In some cases, we might only want to use the name of a function. However, currently the function is always completed with parenthesis and parameters. An example is as follows:

Can we add an option like pylsp.plugins.jedi_completion.include_class_objects to add function objects as a separate completion item?

Hey @llan-ml, thanks for reporting. Unfortunately, we're don't have much free time to add an option for this. But you're welcome to send us a pull request that implements it.

Otherwise, I suggest to use the option pylsp.plugins.jedi_completion.include_params to disable parameters in completions.

Hi @ccordoba12, I create a PR #246 to add this feature.
