Move resource inheritance class to engine/resources

Move the resources which inherit from 'Resource'
to engine/resources, such as stack_resource,
stack_user and signal_responder, and move
non-resources to engine/, such as iso_8601.py module.

Change-Id: Ic26c34cc8d34ca03ce674dc8c6ac32c10885b75f
Implements: blueprint reorganize-resources-code-structure
