[CLI] Most of the ssl-manage commands doesn't work for not initialized clusters

couchbase-cli ssl-manage -c 127.0.0.1:9002 -u Administrator -p asdasd --cluster-ca-load

ERROR: Cluster is not initialized, use cluster-init to initialize the cluster

Seems like admin should be able to modify all the ssl-manage settings for not initialized clusters (at least ns_server doesn't have any limitations in this area)

I think this issue needs to be fixed in 7.1.1 because it prevents users from provisioning nodes with certificates before adding them to a cluster. Basically users are forced to use REST API instead of CLI currently.
