Organizations: Organization chooser page (#10325)
* Initial work for an all-purporse URL scheme for organization-specific pages
* Split out handling of querystring
* Adds organization chooser step (>1 organization), use `-` as "unspecified" slug
* Do not handle additional kwargs, it's meaningless. Raise 404 and log a warning.
* Handle 'next_name' kwarg in tests, handle NoReverseMatch by raising 404
* Setup initial test cases
* Test case to ensure that the chooser list is empty when there's no organization membership
* Add further test assertions
* Update readthedocs/organizations/templates/organizations/organization_choose.html
