Subject: [PATCH] Remove `:managed_config` option.

In practice, it was already removed half a year ago, but the description
 and cheatsheet entries were still there.

The migration intentionally does not use ConfigDB.get_by_params, since
this will break migration code as soon as we add a new field is added
 to ConfigDB.

Closes #2086

+switched to a new configuration mechanism, however it was not officially removed until now.
 
 ### Changed
 - Minimum lifetime for ephmeral activities changed to 10 minutes and made configurable (`:min_lifetime` option).
