Create ransack helper to auto-create the query arguments from `ransackable_attributes` and maybe `ransackable_associations`

[adrianthedev]

Feature

Instead of duplicating the code and having a big query method, create a helper that will output all the attributes from ransackable_attributes. Maybe add an option for associations.

# instead of 
query.ransack(company_name_cont: params[:q], user_first_name_cont: params[:q], user_last_name_cont: params[:q], user_phone_cont: params[:q], user_username_cont: params[:q], requester_first_name_cont: params[:q], requester_last_name_cont: params[:q], requester_phone_cont: params[:q], requester_username_cont: params[:q], m: "or").result(distinct: false)

# have this
query.ransack(compile_ransack_attributes_for(User)).result(distinct: true)
