OP-589 change user password

• Import status from rest_framework instead of every status separately

• Add update view to change the password by updating a user

• Allow changing the user data only for the user himself or an administrator

• Move functionality to do a request into a separate method to reduce code duplication and ease the handling of the authentication methods (with auth token or username and password)

• Add username and password parameter to send_request method

• Refactor send_request method:

  • Convert 'data', 'obj_id' and 'search_param' to real parameters instead of reading them from the kwargs

  • Use .format method to concatenate strings

  • Convert double quotes to single quotes

• Add Gatling tests

• Refactor some older Gatling tests to expect an error response dictionary and not just a string
