Checkmk Werk 15188: setting empty user passwords via the REST API

ID: 15188 Title: setting empty user passwords via the REST API Component: REST API Level: 1 Class: Bug fix Version: 2.3.0b1 Prior to this Werk it was possible to set empty passwords for users via the REST API. An empty password is not considered a valid password and now results in a 400 error. Note that this only affected the REST API, not the UI's User Management nor it's Change Password functionality.
