london-a: disable unused services (InfluxDB, Redis, PostgreSQL, libvirtd) (#37)

Browse source 
Services stopped and disabled in rc.conf on london-a.
Removed audit variables from host_vars, replaced with cleanup note.

All four were leftovers from a defunct pez_vps project:
- InfluxDB: no user databases, only _internal
- Redis: empty keyspace, no clients
- PostgreSQL: defunct pez_vps database (Pez approved removal)
- libvirtd: zero VMs defined

Resolves PESO-113
