couchbase-cli does not allow to set index_path separately from data path( --node-init-data-path sets for both data and index paths)

now we can set only --node-init-data-path, for example:

./couchbase-cli node-init -c localhost:8091 -u Administrator -p password --node-init-data-path=/tmp

at the same time we can set via rest API different or separate values:

[root@cen-2708 bin]# curl -i --data "path=%2Ftmp%2Fa&index_path=%2Ftmp%2Fb" "http://Administrator:password@10.3.121.68:8091/nodes/self/controller/settings"

EXAMPLES:
List servers in a cluster:
couchbase-cli server-list -c 192.168.0.1:8091

Server information:
couchbase-cli server-info -c 192.168.0.1:8091

Add a node to a cluster, but do not rebalance:
couchbase-cli server-add -c 192.168.0.1:8091 \
--server-add=192.168.0.2:8091 \
--server-add-username=Administrator \
--server-add-password=password

Add a node to a cluster and rebalance:
couchbase-cli rebalance -c 192.168.0.1:8091 \
--server-add=192.168.0.2:8091 \
--server-add-username=Administrator \
--server-add-password=password

Remove a node from a cluster and rebalance:
couchbase-cli rebalance -c 192.168.0.1:8091 \
--server-remove=192.168.0.2:8091

Remove and add nodes from/to a cluster and rebalance:
couchbase-cli rebalance -c 192.168.0.1:8091 \
--server-remove=192.168.0.2 \
--server-add=192.168.0.4 \
--server-add-username=Administrator \
--server-add-password=password

Stop the current rebalancing:
couchbase-cli rebalance-stop -c 192.168.0.1:8091

Change the username, password, port and ram quota:
couchbase-cli cluster-init -c 192.168.0.1:8091 \
--cluster-init-username=Administrator \
--cluster-init-password=password \
--cluster-init-port=8080 \
--cluster-init-ramsize=300

Change the data path:
couchbase-cli node-init -c 192.168.0.1:8091 \
--node-init-data-path=/tmp

List buckets in a cluster:
couchbase-cli bucket-list -c 192.168.0.1:8091

Create a new dedicated port couchbase bucket:
couchbase-cli bucket-create -c 192.168.0.1:8091 \
--bucket=test_bucket \
--bucket-type=couchbase \
--bucket-port=11222 \
--bucket-ramsize=200 \
--bucket-replica=1
