Fix CATS failure: test broker config
Fix CATS failure: test broker config

- Issue was caused because A1 already had a broker with the default sso
  client id. The private broker test was pushing a broker without
  updating it to use random values. This caused a validation failure for
  duplicate dashboard client ids.
