Currently we can't set server groups and server group members quotas in Horizon, they are still the back end definition of default. In some cases, it will failed to create an instance when server group members quota is insufficient. Therefore, it is necessary to specify the quota of the server groups and server group members when creating and editing the project. This patch allows the user to modify the default values for the server groups and the server group members quota. Change-Id: Ifbd51bec3e775d8fecbf110da37309a443a3d1ba Closes-Bug:#1732429
