Couchbase should not listen by default on all server IPs

[yurem]

By default Couchbase server listens on all IPs. It's unsecure. On the other extreme we should allow Couchbase to work in cluster. In any case I offer to reconfigure it to listen only on localhost by default.

I could not fin a way to change bind address of couchbase services. I am afraid there is no way to change.

In this case I think we need to add information about opened ports at the end of Couchbase install before notes about Couchbase license.

Maybe just show Couchabse info in console? It should be usefull for admin. Sample from my VM:

Warning: Swappiness is not set to 0.
Please look at https://developer.couchbase.com/documentation/server/current/install/install-swap-space.html as for how to PERMANENTLY alter   this setting.
