''' Get cdist_object parameters dict adopted by context.
Context consists of cdist_type boolean, optional, required,
optional_multiple and required_multiple parameters. If parameter
is multiple parameter then its value is a list.
This adaptation works on cdist_object.parameters which are read from
directory based dict where it is unknown what kind of data is in
file. If there is only one line in the file it is unknown if this
is a value of required/optional parameter or if it is one value of
multiple values parameter.
