When selectively stopping Connect, CLI also stops ksql-server and Confluent Control Center

[rmoff]

If I selectively shutdown Connect, CLI also stops ksql-server and Confluent Control Center.

Robin@asgard02 ~> confluent status
control-center is [UP]
ksql-server is [UP]
connect is [UP]
kafka-rest is [UP]
schema-registry is [UP]
kafka is [UP]
zookeeper is [UP]
Robin@asgard02 ~> confluent stop connect
Using CONFLUENT_CURRENT: /var/folders/q9/2tg_lt9j6nx29rvr5r5jn_bw0000gp/T/confluent.6yVWsyCf
Stopping control-center
control-center is [DOWN]
Stopping ksql-server
ksql-server is [DOWN]
Stopping connect
connect is [DOWN]
Robin@asgard02 ~> confluent status
control-center is [DOWN]
ksql-server is [DOWN]
connect is [DOWN]
kafka-rest is [UP]
schema-registry is [UP]
kafka is [UP]
zookeeper is [UP]

(If I selectively startup Connect, CLI does not change the state of ksql-server or Confluent Control Center)
