Fix double index entry

We cannot use ..only.. with a toctree, it gets parsed at the wrong
time.

Add a second Debian specific index file so that Debian gets only this
file. This avoids the double index entry in the sidetable but leads to
no index table for Debian.

+needs. These projects include Compute, Identity Service, Networking,
+Image Service, Block Storage, Object Storage, Telemetry,
+Orchestration, and Database. You can install any of these projects
+separately and configure them stand-alone or as connected entities.
