[PY-623] Get team properties backported to client

[saurbhc]

Problem

Will need to backport some api calls to client class, getting team properties which will be defined in future code.

Solution

• add client.get_team_properties method
• backport future client

TODO:

• Merge [py-578][py-580] get properties endpoints #747 to master before merging this PR.

PY-623 client.get_team_properties

[Nathanjp91]

Would like to see a test (in future tests module) re config from old as well as tests in the older code in the style of responses. We're introducing api calls for properties that clients will be using so need to make reasonably sure that they don't break if we change things in darwin.future now.

Looks good: I renamed include_options -> include_property_values because of discussion on project_properties about removing 'options' from the objects in favour of property_values instead. So just to keep consistency
