@ofedoren what do you think about this help:

Option details:
Following parameters accept format defined by its schema (bold are required, parameter_name and value must be a string):

--typed-parameters "name=<parameter_name>,value=<parameter_value>,parameter_type=[string || int ...]] "

@shiramax, thanks for your effort to make UX better!

I agree that it will help users, but what if we go further and show something even more verbose?

  Following parameters accept format defined by its schema (bold are required; <> contain acceptable type; [] contain acceptable value):

  --typed-parameters  "name=<string>\,value=<string>\,parameter_type=[string|boolean|integer|real|array|hash|yaml|json]\,hidden_value=[true|false|1|0], ... "

Please tell me what do you think about that :)

@shiramax, updated :) I've added a way to show mentioned help, so when you have time please check it (with theforeman/hammer-cli-foreman#448 for example) and tell me if it's better.
