clusterinit CLI has inconsistency between example and real help

cluster-* OPTIONS:
--cluster-username=USER new admin username
--cluster-password=PASSWORD new admin password
--cluster-port=PORT new cluster REST/http port
--cluster-ramsize=RAMSIZEMB per node ram quota in MB

While example suggest:

Set the username, password, port and ram quota:
couchbase-cli cluster-init -c 192.168.0.1:8091 \
--cluster-init-username=Administrator \ ----> Help shows --cluster-username, while here it is --cluster-init-username
--cluster-init-password=password \
--cluster-init-port=8080 \
--cluster-init-ramsize=300

change the cluster username, password, port and ram quota:
couchbase-cli cluster-edit -c 192.168.0.1:8091 \
--cluster-username=Administrator1 \
--cluster-password=password1 \
--cluster-port=8080 \
--cluster-ramsize=300 \
-u Administrator -p password
