Capability update process
A capability update process is a combination of capability assignment and capability remove processes, where unmodified capabilities and corresponding keycloak permissions remain intact.
User
Capability assignment process
safeCreate flag is used only internally, for outside requests a user must always assign a set of new capability ids, if not - an update operation allows the creation and delete capabilities in a single request
