IdoMysqlConnection, IdoPgsqlConnection, IcingaDB, and ElasticsearchWriter
require passwords in their configuration to authenticate against external
services. This commit ensures that these can no longer be accessed using the
API.
This patch ensures that specific configuration types
are pre-activated and post-activated. In general,
logging is first, then common configuration objects
like host/service, downtimes, etc.
In the end, all features are activated after to ensure
that notifications are only sent once downtimes are applied.
A similar thing happens for starting with checks too early.
The ApiListener feature runs first to allow cluster connections
at first glance.

This better reflects its purpose as otherwise it would imply
that you need Elastic Stack for it. Graylog also reads from
Elasticsearch instances, this could serve as additional integration
here.
