update keycloak tests

[ScharfViktor]

Added:

• Keycloak tests rewritten. We create all data in Keycloak-ldap and verify that users/groups with the correct permissions are available in OpenCloud.
• keycloak api steps for:
  creating group
  adding group role
  adding user to group
  delete group
• the provision steps which API to use (Graph or Keycloak) have been removed.Now we explicitly specify this in the step definition.
• for admin steps in the step definitions deleted step user. No user choice. There is always an admin.
• enable tests in CI

• This error message is used in deleteGroup and is misleading. Update it to something like 'Failed while deleting group'.
