Can add --services in couchbase-cli cluster and node-init help sections

With the latest couchbase version, the option of services-init="data;query;index" is not displayed on help.

Nice to add this, so people are aware of the services options while starting up a cluster_init.

Example:
./couchbase-cli cluster-init -h
couchbase-cli - command-line cluster administration tool

CLUSTER:
--cluster=HOST[:PORT] or -c HOST[:PORT]

OPTIONS:
-u USERNAME, --user=USERNAME admin username of the cluster
-p PASSWORD, --password=PASSWORD admin password of the cluster
-o KIND, --output=KIND KIND is json or standard
-d, --debug
-s, --ssl uses SSL for communication with secure servers

Something like
./couchbase-cli cluster-init -c 10.6X.X:8091 --cluster-init-ramsize=2000 -u Administrator -p password --services="data;query"
