this is all irrelevant or duplicated:
- dbreco.rst
- duplicates supported databases in admin-guide
- ceilometer to gnocchi section is old and deck doesn't really
reflect current gnocchi. also, all ocata+ docs install
gnocchi by default.
- custom.rst
- duplicates telemetry-data-pipelines in admin-guide
- dups best practices in admin-guide with shuffle option
- upgrade.rst
- upgrade is just stop, upgrade, restart for each service
- nothing is unique except notification agent with partitioning[1]
and existing stuff doesn't address it.
