[CX] Finalize ports

Finalize port for analytics service to listen on for end user requests, for example, to run queries from an SDK. I propose using 8095 (and 18095 for HTTPS).

Main REST port for ns_server is 8091
CAPI 8092
N1QL 8093
FTS 8094

The secure version of these ports for https calls is 18091 / 18092 / 18093 / 18094 etc.

The port 8095 was used by CBFT when build in standalone mode (and still is). There's a ticket to change this MB-20398 but this is non-blocking.
