This commit better separates the Metadata class model from the
Metadata wireline format, by tailoring the constructors
towards class-based parameters and adding an additional
factory classmethod that creates Metadata objects based on the
wireline json/dictionary metadata representation. (pythonic
way of constructor overloading).
This 'from_dict' factory method recurses into the 'from_dict'
methods of each contained complex field/attribute that is also
represented by a class. Currently 'signed' is the only such
attribute.
This commit further:
- Changes optional constructor keyword arguments to mandatory
positional arguments: Reduces code and simplifies usage by
restricting it. For now, users are unlikely to call
constructor directly anyway, but the 'from_dict' factory (or
its 'from_json_file' wrapper) instead.
- Removes Signed.__expiration (datetime) vs. Signed.expires
(datestring) dichotomy: Keeping only one representation of the
same attribute in memory makes the interface simpler and less
ambiguous. We choose the datetime object, because it is more
convenient to modify. Transformation from and to the string
format required by the tuf wireline format is performed in the
corresponding metadata de/serialization methods, i.e.
('to_dict' and 'from_dict').
