pyinvoke: pass any number and name of arguments not specified in task definition

Question

I'd like to make a generic task, something like

# tasks.py
from invoke import task
@task
def do(context, **kwargs):
   print("Kwargs")
   print(kwargs)

so I can pass any name and number of arguments to this task

inv do
inv do --image=./path/to/image
inv do --text="Hi"
inv do --image=./path/to/image --text='Hi 2'
inv do --data=./path/to/csv

also options without values if possible

inv do --text="hi" --silent
