Change port command from CLI not working with 7.0.0 build 5071

Steps to reproduce the issue:

1. Install the cb version 7.0.0-5071 build on VM using below script.

python3 scripts/new_install.py -i /tmp/testRunner.ini -p timeout=1800,skip_local_download=False,get-cbcollect-info=True,version=7.0.0-5071,product=cb,debug_logs=True,ntp=True,url=

2. Setup the cluster and add nodes with it. 

2. Now try to change the port with below command

Command:

/opt/couchbase/bin/couchbase-cli cluster-edit -c http://localhost:8091 -u Administrator -p password --cluster-port=9090

Output:

['DEPRECATED: Please use the setting-cluster command instead', 'SUCCESS: Cluster settings modified']

Issue: Port 9090 is not working. Still 8091 is active

3. Try new command as well

Command

/opt/couchbase/bin/couchbase-cli cluster-edit -c http://localhost:8091 -u Administrator -p password --cluster-port=9090

DEPRECATED: Please use the setting-cluster command instead

SUCCESS: Cluster settings modified

[root@s10356-w12r2 ~]# /opt/couchbase/bin/couchbase-cli  setting-cluster -c http://localhost:8091 -u Administrator -p password --cluster-port=9090

SUCCESS: Cluster settings modified

Issue: Port 9090 is not working. Still 8091 is active
