Changes

Project template classes have been added to objects/templates.py and their respective managers added to the Project class in objects/projects.py to represent the project templates API.

The project merge request template, in particular, will facilitate creating merge requests with a description template, like the following example:

mr_description_template = project.merge_request_templates.get("Default")
mr = project.mergerequests.create({'source_branch': 'cool_feature',
                                   'target_branch': 'main',
                                   'title': 'merge cool feature',
                                   'description': mr_description_template.content})
