Assign users to a project

We have added new endpoints to add or remove assigned users to projects.

Here is how you can assign a user to a project:

PUT /v2/projects/:id/assigned_users/:user_id

To remove an already assigned user, you can call this endpoint like so:

DELETE /v2/projects/:id/assigned_users/:user_id

To see the assigned users for a project, just call this endpoint:

GET /v2/projects/:id/assigned_users
